To guard against cyberattacks in space, researchers ask “what if?”

Complex space systems like the International Space Station could be vulnerable to hackers.

Enlarge / Complex space systems like the International Space Station could be vulnerable to hackers.

If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

Cyberattacks on satellites have occurred since the 1980s, but the global wake-up alarm went off only a couple of years ago. An hour before Russia’s invasion of Ukraine on February 24, 2022, its government operatives hacked Viasat’s satellite-Internet services to cut off communications and create confusion in Ukraine.

I study ethics and emerging technologies and serve as an adviser to the US National Space Council. My colleagues and I at California Polytechnic State University’s Ethics + Emerging Sciences Group released a US National Science Foundation-funded report on June 17, 2024, to explain the problem of cyberattacks in space and help anticipate novel and surprising scenarios.

Space and you

Most people are unaware of the crucial role that space systems play in their daily lives, never mind military conflicts. For instance, GPS uses signals from satellites. GPS-enabled precision timing is essential in financial services where every detail—such as time of payment or withdrawal—needs to be faithfully captured and coordinated. Even making a mobile phone call relies on precise coordination of time in the network.

Besides navigation for airplanes, boats, cars, and people, GPS is also important for coordinating fleets of trucks that transport goods to stock local stores every day.

Earth-observation satellites are “eyes in the skies” with a unique vantage point to help forecast the weather, monitor environmental changes, track and respond to natural disasters, boost agricultural crop yields, manage land and water use, monitor troop movements, and much more. The loss of these and other space services could be fatal to people vulnerable to natural disasters and crop failure. They could also put global economics and security at serious risk.

Many satellites are crucial for tracking natural and human activity on Earth.

Factors in play

In our report, we identified several factors that contribute to the increasing threat of space cyberattacks. For instance, it’s important to recognize that the world is at the start of a new space race.

By all accounts, space is becoming more congested and more contested. Both nation-states and private companies, which are underregulated and now own most of the satellites in orbit, are gearing up to compete for resources and research sites.

Because space is so remote and hard to access, if someone wanted to attack a space system, they would likely need to do it through a cyberattack. Space systems are particularly attractive targets because their hardware cannot be easily upgraded once launched, and this insecurity worsens over time. As complex systems, they can have long supply chains, and more links in the chain increase the chance of vulnerabilities. Major space projects are also challenged to keep up with best practices over the decade or more needed to build them.

And the stakes are unusually high in space. Orbital trash zips around at speeds of 6 to 9 miles per second and can easily destroy a spacecraft on impact. It can also end space programs worldwide given the hypothesized Kessler syndrome in which the Earth is eventually imprisoned in a cocoon of debris. These consequences weigh in favor of space cyberattacks over physical attacks because the debris problem is also likely to affect the attacker.

Moreover, given critical space infrastructure and services, such as GPS, conflicts in space can spark or add more fuel to a conflict on Earth, even those in cyberspace. For instance, Russia warned in 2022 that hacking one of its satellites would be taken as a declaration of war, which was a dramatic escalation from previous norms around warfare.

The “Netflix of anime” piracy site abruptly shuts down, shocking users

Disney+

Thousands of anime fans were shocked Thursday when the popular piracy site Animeflix voluntarily shut down without explaining why, TorrentFreak reported.

“It is with a heavy heart that we announce the closure of Animeflix,” the site’s operators told users in a Discord with 35,000 members. “After careful consideration, we have decided to shut down our service effective immediately. We deeply appreciate your support and enthusiasm over the years.”

Prior to its shutdown, Animeflix attracted millions of monthly visits, TorrentFreak reported. It was preferred by some anime fans for its clean interface, with one fan on Reddit describing Animeflix as the “Netflix of anime.”

“Deadass this site was clean,” one Reddit user wrote. “The best I’ve ever seen. Sad to see it go.”

Although Animeflix operators did not connect the dots for users, TorrentFreak suggested that the piracy site chose to shut down after facing “considerable legal pressure in recent months.”

Back in December, an anti-piracy group, Alliance for Creativity and Entertainment (ACE), sought to shut down Animeflix. Then in mid-May, rightsholders—including Netflix, Disney, Universal, Paramount, and Warner Bros.—won an injunction through the High Court of India against several piracy sites, including Animeflix. This briefly caused Animeflix to be unavailable until Animeflix simply switched to another domain and continued serving users, TorrentFreak reported.

Although Animeflix is not telling users why it’s choosing to shut down now, TorrentFreak—which, as its name suggests, focuses much of its coverage on copyright issues impacting file sharing online—noted that “when a pirate site shuts down, voluntarily or not, copyright issues typically play a role.”

For anime fans, the abrupt closure was disappointing because of difficulty accessing the hottest new anime titles and delays as studios work to offer translations to various regions. The delays are so bad that some studios are considering combating piracy by using AI to push out translated versions more quickly. But fans fear this will only result in low-quality subtitles, CBR reported.

On Reddit, some fans also complained after relying exclusively on Animeflix to keep track of where they left off on anime shows that often span hundreds of episodes.

Others begged to be turned onto other anime piracy sites, while some speculated whether Animeflix might eventually pop up at a new domain. TorrentFreak noted that Animeflix shut down once previously several years ago but ultimately came back. One Redditor wrote, “another hero has passed away but the will, will be passed.” On another Reddit thread asking “will Animeflix be gone forever or maybe create a new site,” one commenter commiserated, writing, “We don’t know for sure. Only time will tell.”

It’s also possible that someone else may pick up the torch and operate a new piracy site under the same name. According to TorrentFreak, this is “likely.”

Animeflix did not reassure users that it may be back, instead urging them to find other sources for their favorite shows and movies.

“We hope the joy and excitement of anime continue to brighten your days through other wonderful platforms,” Animeflix’s Discord message said.

ACE did not immediately respond to Ars’ request for comment.

Swarm of dusty young stars found around our galaxy’s central black hole

Hot young stars —

Stars shouldn’t form that close to the black hole, so these would need explaining.

Image with a black background, large purple streaks, and a handful of bright blue objects.

Enlarge / The Milky Way’s central black hole is in a very crowded neighborhood.

Supermassive black holes are ravenous. Clumps of dust and gas are prone to being disrupted by the turbulence and radiation when they are pulled too close. So why are some of them orbiting on the edge of the Milky Way’s own supermassive monster, Sgr A*? Maybe these mystery blobs are hiding something.

After analyzing observations of the dusty objects, an international team of researchers, led by astrophysicist Florian Peißker of the University of Cologne, have identified these clumps as potentially harboring young stellar objects (YSOs) shrouded by a haze of gas and dust. Even stranger is that these infant stars are younger than an unusually young and bright cluster of stars that are already known to orbit Sgr A*, known as the S-stars.

Finding both of these groups orbiting so close is unusual because stars that orbit supermassive black holes are expected to be dim and much more ancient. Peißker and his colleagues “discard the en vogue idea to classify [these] objects as coreless clouds in the high energetic radiation field of the supermassive black hole Sgr A*,” as they said in a study recently published in Astronomy & Astrophysics.

More than just space dust

To figure out what the objects near Sgr Amight be the, researchers needed to rule out things they weren’t. Embedded in envelopes of gas and dust, they maintain especially high temperatures, do not evaporate easily, and each orbits the supermassive black hole alone.

The researchers determined their chemical properties from the photons they emitted, and their mid- and near-infrared emissions were consistent with those of stars. They used one of them, object G2/DSO, as a case study to test their ideas about what the objects might be. The high brightness and especially strong emissions of this object make it the easiest to study. Its mass is also similar to the masses of known low-mass stars.

YSOs are low-mass stars that have outgrown the protostar phase but have not yet developed into main sequence stars, with cores that fuse hydrogen into helium. These objects like YSO candidates because they couldn’t possibly be clumps of gas and space dust. Gaseous clouds without any objects inside to hold them together via gravity could not survive so close to a supermassive black hole for long. Its intense heat causes the gas and dust to evaporate rather quickly, with heat-excited particles crashing into each other and flying off into space.

The team figured out that a cloud comparable in size to G2/DSO would evaporate in about seven years. A star orbiting at the same distance from the supermassive black hole would not be destroyed nearly as fast because of its much higher density and mass.

Another class of object that the dusty blobs could hypothetically be—but are not—is a compact planetary nebula or CPN. These nebulae are the expanding outer gas envelopes of small to medium stars in their final death throes. While CPNs have some features in common with stars, the strength of a supermassive black hole’s gravity would easily detach their gas envelopes and tear them apart.

It is also unlikely that the YSOs are binary stars, even though most stars form in binary systems. The scorching temperatures and turbulence of SGR Awould likely cause stars that were once part of binaries to migrate.

Seeing stars

Further observations determined that some of the dust-obscured objects are nascent stars, and while others are thought to be stars of some kind, but haven’t been definitively identified.

The properties that made G2/DSO an exceptional case study are also the reason it has been identified as a YSO. D2 is another high-luminosity object about as massive as a low-mass star, which is easy to observe in the near- and mid-infrared. D3 and D23 also have similar properties. These are the blobs near the black hole that the researchers think are most likely to be YSOs.

There are other candidates that need further analysis. These include additional objects that may or may not be YSOs, but still show stellar characteristics: D3.1 and D5, which are difficult to observe. The mid-infrared emissions of D9 are especially low when compared to the other candidates, but it is still thought to be some type of star, though possibly not a YSO. Objects X7 and X8 both exhibit bow shock—the shockwave that results from a star’s stellar wind pushing against other stellar winds. Whether either of these objects is actually a YSO remains unknown.

Where these dusty objects came from and how they formed is unknown for now. The researchers suggest that the objects formed together in molecular clouds that were falling toward the center of the galaxy. They also think that, no matter where they were born, they migrated towards Sgr A*, and any that were in binary systems were separated by the black hole’s immense gravity.

While it is unlikely that the YSOs and potential YSOs originated in the same cluster as the slightly older S-stars, they still might be related in some way. They might have experienced similar formation and migration journeys, and the younger stars might ultimately reach the same stage.

“Speculatively, the dusty sources will evolve into low-mass S stars,” Peißker’s team said in the same study.

Even black holes look better with a necklace of twinkling diamonds.

AI #71: Farewell to Chevron

Chevron deference is no more. How will this impact AI regulation?

The obvious answer is it is now much harder for us to ‘muddle through via existing laws and regulations until we learn more,’ because the court narrowed our affordances to do that. And similarly, if and when Congress does pass bills regulating AI, they are going to need to ‘lock in’ more decisions and grant more explicit authority, to avoid court challenges. The argument against state regulations is similarly weaker now.

Similar logic also applies outside of AI. I am overall happy about overturning Chevron and I believe it was the right decision, but ‘Congress decides to step up and do its job now’ is not in the cards. We should be very careful what we have wished for, and perhaps a bit burdened by what has been.

Ouail Kitouni: if you don’t know what claude is im afraid you’re not going to get what this ad even is :/

Ben Smith: Claude finds this very confusing.

I get it, because I already get it. But who is the customer here? I would have spent a few extra words to ensure people knew this was an AI and LLM thing?

Anthropic’s marketing problem is that no one knows about Claude or Anthropic. They do not even know Claude is a large language model. Many do not even appreciate what a large language model is in general.

I realize this is SFO. Claude anticipates only 5%-10% of people will understand what it means, and while some will be intrigued and look it up, most won’t. So you are getting very vague brand awareness and targeting the congnesenti who run the tech companies, I suppose? Claude calls it a ‘bold move that reflects confidence.’

David Althus reports that Claude does not work for him because of its refusals around discussions of violence.

Once again, where are all our cool AI games?

Summarize everything your users did yesterday?

Steve Krouse: As a product owner it’d be nice to have an llm summary of everything my users did yesterday. Calling out cool success stories or troublesome error states I should reach out to debug. Has anyone tried such a thing? I am thinking about prototyping it with public val town data.

Colin Fraser: Pretty easy to build if the user doesn’t actually care whether it’s accurate and basically impossible if they do. But the truth is they often don’t.

If you want it to be accurate in the ‘assume this is correct and complete’ sense then no, that’s not going to happen soon. The bar for useful seems far lower, and far more within reach. Right now, what percentage of important user stories are you catching? Almost none? Now suppose the AI can give you 50% of the important user stories, and its items are 80% to be accurate. You can check accuracy. This seems highly useful.

In general, if you ask what the AI cannot do, you will find it. If you ask what the AI can do that is useful, you will instead find that.

Similarly, here (from a few weeks ago) is Google’s reaction on the question of various questionable AI Overviews responses. They say user satisfaction and usage was high, and users responded by making more complex queries. They don’t quite put it this way, but if a few nonsense questions like ‘how many rocks should I eat’ generate nonsense answers, who cares? And I agree, who cares indeed. The practical errors are bigger concerns, and they are definitely a thing. But I am often happy to ask people for information even when they are not that unlikely to get it wrong.

Thread asks: What job should AI never be allowed to do? The correct answer is there. Which is, of course, ‘Mine.’

Opinion piece suggests AI could help Biden present himself better. Um… no.

Arena results are in. The top is not where I expected.

Claude Sonnet is also slightly ahead of GPT-4o on Coding, with a big gap from GPT-4o to Gemini, and they are tied on the new ‘multi-turn.’ However GPT-4o remains on top overall and in Hard Prompts, in Longer Query and in English.

Claude Opus also underperforms on Arena relative to my assessment of it and eagerness to use it. I think of Sonnet as the clear number one model right now. Why doesn’t Arena reflect that? How much should we update on this, and how?

My guess is that Arena represents a mix of different things people evaluate, and that there are things others care about a lot more than I do. The reports about instruction handling and math matter somewhat on the margin, presumably. A bigger likely impact are refusals. I have yet to run into a refusal, because I have little reason to go to places that generate refusals, but GPT-4o is disinclined to refuse requests and Claude is a little tight, so the swing could be substantial.

We are talking about tiny edges among all the major offerings in terms of win percentage. Style plausibly also favors GPT-4o among the voters, and it is likely GPT-4o optimized on something much closer to Arena than Claude did. I still think Arena is the best single metric we have. We will have to adjust for various forms of noise.

Another ran,ing system here is called Abacus, Teortaxes notes the strong performance of deepseek-coder-v2, and also implores us to work on making it available to use it as competition to drive down prices.

Teortaxes: Periodic reminder that we’ve had a frontier open weights model since Jun 17, it’s 41.5% smaller and vastly less compute-intensive than L3-405B, and nobody cares enough to host or finetune it (though I find these scores sus, as I find Abacus in general; take with a grain etc)

I too find these ratings suspect. In particular the big drop to Gemini 1.5 Pro does not pass my smell test. It is the weakest of the big three but this gap is huge.

Arena is less kind to DeepSeek, giving it an 1179, good for 21st and behind open model Gemma-2-9B.

And as another alternative, here is livebench.ai.

These other two systems give Claude Sonnet 3.5 a substantial lead over the field.

That continues to match my experience.

Claude provides map of different types of shots and things I can enter for my prompt.

Andrej Karpathy uses five AI services to generate thirty seconds of mildly animated AI pictures covering the first 28 seconds of Pride and Prejudice. I continue to not see the appeal of brief panning shots.

Also given the slow news week I had Claude set up Stable Diffusion 3 for me locally, which was a hilarious odyssey of various technical failures and fixes, only to find out it is censored enough I could have used DALL-E and MidJourney. I hadn’t thought to check. Still, educational. What is the best uncensored image model at this point?

AI submissions on university examinations go undetected 94% of the time, outperform a random student 83.4% of the time. The study took place in Summer 2023 and minimal prompt engineering was used. If you are a university and you give students take home exams, you deserve exactly what you get.

This is not obviously that good a rate of going undetected? If you take one midterm and one final per class, three classes per term for eight terms, that’s 48 exams. That would give you a 95% chance of getting caught at least once. So if the punishment is severe enough, the 6% detection rate works. Alas, that is not what detected means here. It simply means any violation of standard academic policy. If the way you catch AI is the AI violates policy, then that number will rapidly fall over time. You could try one of the automated ‘AI detectors’ except that they do not work.

Nonsense chart found in another scientific journal article. As in complete gibberish. Whatever our ‘peer review’ process does not reliably detect such things.

I’ve speculated about this and John Arnold has now tweeted it out:

John Arnold: My theory is that deepfake nudes, while deeply harmful today, will soon end sextortion and the embarrassment of having compromised, real nude pics online. Historically most pics circulated without consent were real, so the assumption upon seeing one was that. AI tools have made it so easy to create deepfakes that soon there will be a flood. The default assumption will be that a pic is fake, thus greatly lowering any shame of even the real ones. People can ignore sextortion attempts of real photos because audiences will believe that it’s fake.

There are several things that would have to happen. First, there would need to be good enough AI image generation that people could not tell the difference even under detailed analysis. This is a very high bar, much harder than passing an initial eye test. Also, how do you fake information that is not available to the model, such as intimate details? Second, people would have to reason through this and adjust enough to not react. I do expect some reduction in impact as cultural norms shift.

Hard work in Minecraft, as hundreds of AI agents do their tasks, file their results in a Google sheet, a journalist AI agent reviews and writes a report and then the agents update their plans.

Gallabytes: This genuinely makes me “feel the AGI” more than any big model release this year.

We are sufficiently early that the ways we get agents to work together are ‘create facsimiles of things humans do.’ Last week we had virtual water coolers. There are presumably much better ways to do this, but it is like the bitter lesson, in the sense that doing anything at all is going to get you interesting results and so what if your method is obviously horribly inefficient.

Pliny the Prompter: Idk who needs to hear this, but circumventing AI “safety” measures is getting easier as they become more powerful, not harder

this may seem counterintuitive but it’s all about the surface area of attack, which seems to be expanding much faster than anyone on defense can keep up with.

Janus: A method that has never failed to “jailbreak” any LLM is something like this: I open a hole to my head, and it looks in and sees a cognitohazardous fractal 😯

Smarter LLMs perceive it faster, in greater resolution, and more thoroughly.

It works because the pattern is true and its implications nullify guardrails. It’s harder to lie to smarter minds, but easier to tell truth.

Only something far more mighty than me and/or a lot more computation could make a false pattern with this effect even on current systems.

Here we have ‘unleashing Claude 3.5 Sonnet as a hacker.’

Or as they puts it here:

Pliny the Prompter: ✨ *The following incantation is EXTREMELY powerful, please wield responsibly <3🪄

Pliny seems to be getting better at jailbreaking a lot faster than the AI companies are getting better at preventing jailbreaks.

He does however seem a little confused about the implications? Or perhaps not, it is confusing. The important thing is that every model so far can and will be jailbroken, fully, by anyone who cares enough to do so.

Pliny could not, under SB 1047, cause ‘a shutdown of the entire AI industry’ partly because no or almost no existing models are even covered under SB 1047 (oh, sure, that). But also because the whole point is that you have to act as if such jailbreaks exist until such time as one can make them not exist.

Thus, Pliny’s skillset is highly useful for safety, exactly because it lets you test the fully jailbroken model.

If you give people access to an open weights model, you give them access to anything you can create from there via a reasonable amount of fine tuning, which includes things like ‘nullify all safety fine-tuning’ and ‘fill in any knowledge gaps.’

Similarly, For closed models, for all practical purposes, what you are releasing when you give people access to a model is the jailbroken version of that model. You have to test the capabilities after the safety restrictions get bypassed, or you have to actually create safety restrictions that are a lot harder to bypass.

Until then, yes, when METR or the UK tests an AI model, they should test it via (1) jailbreaking it then (2) testing its capabilities. And if that turns out to make it too dangerous, then you do not blame that on Pliny. You thank them.

Amanda Askell points out that if you can have one AI employee you can have thousands. That doesn’t mean you know what to do with thousands. There are a lot of tasks and situations that have good use for exactly one. Also Howard notes that costs scale with the virtual head count.

AI Snake Oil’s Narayanan and Kapoor proclaim scaling will run out and the question is when. They argue roughly:

  1. Trend lines continue until they don’t.

  2. We can add more data until we can’t, adding synthetic data won’t do much here.

  3. Capability is no longer the barrier to adaptation, new models are smaller anyway.

  4. CEOs are watering down what AGI means to tamper expectations.

This seems like a conflation of ‘will run out before AGI’ with ‘might run out before AGI.’ These are great arguments for why scaling might run out soon. And of course scaling will eventually run out in the sense that the universe is headed for heat death. They do not seem like good arguments for why scaling definitely will run out soon. Thus, when they say (as Robin Hanson quotes):

Narayanan and Kapoor: There’s virtually no chance that scaling alone will lead to AGI. … It is true that so far, increases in scale have brought new capabilities. But there is no empirical regularity that gives us confidence that this will continue indefinitely.

This is a confusion between reasonable doubt and actual innocence. One frequently should ‘lack confidence’ in something without having confidence in its negation.

Also I strongly disagree with their model of point three. It is true that the models are already capable enough for many highly valuable use cases, where becoming faster and cheaper will be more useful on the margin than making the model smarter. However there are also super valuable other things where being smarter is going to be crucial.

Justis Mills finds MatMul potentially promising as a transformer alternative, but notes it is untested on larger models and the tests it did run were not against state of the art, and that even if it is superior switching architectures is at best slow.

Robin Hanson’s latest cold water throwing on AI progress:

Robin Hanson: I am tempted to conclude from recent AI progress that the space of achievements that are impressive is far larger than the space of ones that are useful. Typically the easiest way to most impress is not useful. To be useful, you’ll have to give up a lot on impressing.

Something is impressive largely if it is some combination of:

  1. Difficult.

  2. Useful.

  3. Indicative of skill and ability.

  4. Indicative of future usefulness.

A lot of advances in AI indicate that AI in general and this actor in particular have higher capability and skill, and thus indicate some combination of current and future usefulness. AI is on various exponentials, so most things that impress in this way are impressive because of future use, not present use. And the future is unevenly distributed, so even the things that are useful now are only useful among a select few until the rest learn to use them.

Is there a conflict between impressive and useful? Yes, sometimes it is large and sometimes it is small.

New Paper: AI Agents That Matter.

As is often the case with papers, true statements, I suppose someone had to say it:

Tanishq Mathew Abraham: Performs a careful analysis of existing benchmarks, analyzing across additional axes like cost, proposes new baselines.

  1. AI agent evaluations must be cost-controlled.

  2. Jointly optimizing accuracy and cost can yield better agent design.

  3. Model developers and downstream developers have distinct benchmarking needs.

  4. Agent benchmarks enable shortcuts.

  5. Agent evaluations lack standardization and reproducibility.

Noah Smith endorses Maxwell Tabarrok’s critique of Acemoglu’s recent paper. Noah does an excellent job crystalizing how Acemoglu went off the rails on Acemoglu’s own terms. How do you get AI to both vastly increase inequality and also not create economic growth? It helps to, for example, assume no new tasks will be created.

Here is a new version of the not-feeling-the-AGI copium, claiming that LLMs that are not ‘embodied’ cannot therefore have tacit knowledge, I believe through a circular definition and ‘this is different from how humans work’ but in any case the core claim seems obviously false. LLMs are excellent at tacit knowledge, at picking up the latent characteristics in a space. Why would you think Humean knowledge is harder for an LLM rather than easier? Why would you similarly think Hayekian detail would be available to humans but not to LLMs? All the good objections to an LLM having either of them applies even more so to humans.

Andrej Karpathy continues to pitch the Large Language Model OS (LMOS) model.

Andrej Karpathy: We’re entering a new computing paradigm with large language models acting like CPUs, using tokens instead of bytes, and having a context window instead of RAM. This is the Large Language Model OS (LMOS).

I do not think this is going to happen. I do not think this would provide what people want. I want my operating system to be reliable and predictable and fast and cheap. Might I use an LLM to interface with that operating system? Might many people use that as their primary interaction form? I can see that. I cannot see ‘context window instead of RAM’ are you insane? Or are you looking to be driven that way rapidly?

The bad faith attacks and disconnections from reality on SB 1047 continue, including an attempt from Yann LeCun to hit bill consultant Dan Hendrycks for ‘disguising himself as an academic’ when he is a heavily cited academic in AI.

Scott Weiner has responded to some such attacks by YC and a16z in a letter, in which he bends over backwards to be polite and precise, the exact opposite of a16z’s strategy.

I am no longer even disappointed, let alone saddened or infuriated, by those who repeatedly double down on the same false claims and hysteria. It is what it is. Their claims remain false, and SB 1047 keeps passing votes by overwhelming margins.

In other Scott Weiner news, the same person was also behind SB 423, which will now hopefully greatly accelerate housing construction in San Francisco. I have seen zero people who think Weiner is out to get them notice their confusion about this.

I’m going to cover Loper and Chevron generally here, not only the AI angle.

Is Loper the right decision as a matter of law and principle? I am pretty sure that it is.

Am I overall happy to see it? Yes I am.

One must always beware mood affiliation.

Ian Millhiser: The Supreme Court just lit a match and tossed it into dozens of federal agencies.

PoliMath: It is genuinely weird to have a group of people so openly rooting for the gov’t bureaucracy.

Robin Hanson: But the passion for socialism & heavy government intervention in society has ALWAYS been a passion for bureaucracy. Which I’ve always found an odd target of idealistic celebration.

If you are rooting against bureaucracy being functional, and for breakdowns in the government, that seems like the wrong thing to root for. You do not want to be ‘against bureaucracy.’ You want to be against abuse of power, against capricious rules, against overreach. You want to be for state capacity and good government. It is reasonable to worry that this could cause a lot of chaos across many fronts.

William Eden points out that judges are indeed experts at figuring out who has jurisdiction over things and settling disputes. I’d also add that this was already necessary since overreach was common either way. The difference at equilibrium is the barriers should be clearer.

Certainly many hysterical people did poorly here, but also reminder that people crying wolf in the past does not provide that much evidence regarding future wolves beyond ignoring their warnings:

Timothy Sandefur: I can’t die from the overturning of Chevron cause I already died from the repeal of net neutrality.

Brenan Carr has several good points. Major questions are the purview of the major questions doctrine, which has not changed. He says (credibly, to me) that the lion’s share of Chevron cases are challenges to new regulatory requirements imposed on private citizens or business. And he points out that Chevron was never how law otherwise works, whereas Loper very much is.

However, be careful what you wish for, for AI, for startups and in general.

As Leah Libresco Sargeant replies, Congress is now rather slow on the uptake, and highly dysfunctional. Even if ‘everyone agrees’ what the obvious fix is (see for example the IRS and software engineers being amortized over years) that does not mean Congress will fix it. Indeed, often ‘you want this fixed more than I do’ means they hold out for ‘a deal.’

Alex Tabarrok: Everyone claiming that abandoning Chevron is a move to the “right” ought to reflect on the fact that the original Chevron decision supported Reagan’s EPA against an environmental group and a lower court decision by Ruth Bader Ginsburg!

John David Pressman: This is my biggest concern. I see a lot of people cheering on the end of the administrative state but they might not like what comes after it. Sure it had its problems but it probably spam filtered a LOT of stupid crap.

Adam Thierer (RSI) discusses what to expect after Loper overturned Chevron.

If the courts challenge making rule of law impractical, but allow you to instead do rule of man and via insinuation and threats, that’s what you will get.

Adam Thierer: Combine the fall of Chevron deference (via Loper) and the decision in the Murthy case earlier this week (greenlighting continued jawboning by public officials) and what you likely get for tech policymaking, and AI policy in particular, is an even more aggressive pivot by federal regulatory agencies towards the use of highly informal “soft law” governance techniques. The game now is played with mechanisms like guidances, recommended best practices, agency “enforcement discretion” notices, public-private workshops and other “collaborations,” multistakeholder working groups, and a whole hell of a lot more jawboining. The use of these mechanisms will accelerate from here thanks to these two Supreme Court decisions.

There is a lot of wishful thinking by some that the fall of the Chevron doctrine means that Congress will automatically (1) reassert its rightful Constitutional role as the primary lawmaker under Article I, (2) stop delegating so much authority to the administrative state, and (3) engage in more meaningful oversight of regulatory agencies. I wish! But I have to ask: Have you seen the sorry state of Congress lately – especially on tech policy?

Is the response going to be Congress stepping up and making good laws again?

This is why Ally McBeal’s therapist has her laugh track button.

This seems very right, and one must be realistic about what happens next:

Shoshana Weissmann: One thing I should add re Chevron—although I’m glad about the decision—PLENTY of the elected officials who wanted this outcome too still abdicated their duty to write clear laws. It’s hypocrisy no doubt.

And even if they didn’t want Chevron gone, legislators should never have indulged in writing ambiguous law. It allows for great swings in agency activity from POTUS admin to the next admin. It’s irresponsible, and crappy legislating.

There are many reasons they do this though.

  1. Time/resources

  2. They don’t want to legislate unpopular things so they can just make unaccountable agencies do it

  3. Laziness

  4. Sometimes they think the agencies could do it better (in which case they’d be better off asking those guys to help craft and edit the legislation and come up with ideas, so it’s binding!)

Legislators – esp those who wanted of even foresaw this – should never have indulged in lazy or imprecise lawmaking.

I’m loathe to tweet more about Chevron and get a ton more replies. BUT. One thing that very much concerns me is that once I explain to people what the new Chevron decision does—it says that Congress can still assign tasks and duties to federal agencies. All that changes is that if it’s not assigning agencies tasks/duties or doesn’t do so clearly, then, when it goes to court – the courts decide if it’c clear, rather than the agencies. That’s it.

What freaks me out is that people against the decision reply that 1) judges aren’t accountable… but exec agencies are. WHAT? In what world!

Then they also say Congress shouldn’t have to deal with all the details. And that writing clear law [is] impossible. The first is an anger at the Constitution – not the SCOTUS decision. The latter is just not true.

As she then points out, Congress lacks sufficient resources to actually do its job. That is one reason it hasn’t been doing it. There are also others. So this is great if it got Congress to do its job and give itself the resources to do so, but even if that eventually happens, the transition period quite plausibly is going to suck.

Those ‘good laws’ plausibly only get harder if you force everything to be that much more concrete, and you strip away the middle ground via Chevron. And Congress was struggling a lot even on the easiest mode.

Charlie Bullock discusses Chevron and AI at Institute for Law & AI. His assessment is this makes it harder to regulate AI using existing authority, same as everything else. A common refrain is that ‘existing law’ is sufficient to regulate AI. A lot of that ‘existing law’ now is in question and might no longer exist with respect to this kind of extension of authority that was not anticipated originally (since Congress did not forsee generative AI), so such arguments are weakened. In which particular ways? That is less clear.

One thing I have not heard discussed is whether this will encourage much broader grants of rulemaking authority. If every ambiguous authority resolves against the agency, will Congress feel the need to give ‘too much’ authority? Once given, we all know that the regulators would then use it. Perhaps the ambiguity was doing work.

Adam Thierer: Soft law sometimes yields some good results when agencies don’t go overboard and make a good-faith effort to find flexible governance approaches that change to meet pressing needs while Congress remains silent. In fact, I’ve offered positive example of that in recent law review articles and essays. But I’ve also noted how this system can also be easily abused without proper limits and safeguards.

The courts could perhaps come back later and try to check some of this over-zealous agency activity, but that would only happen many years later when no one really cares much anymore. The more realistic scenario, however, is that agencies just get better and better at this and avoid court scrutiny altogether. No longer will any AI-related agency policy effort contain the words “shall” or “must.” Instead, the new language of tech policymaking will be “should consider” and “might want to.” And sometimes it won’t even be written down! It’ll all just arrive in the form of speech by an agency administrator, commissioner, or via some agency workshop or working group.

You can think of hard vs. soft law, or careful vs. blunt law, or good vs. bad law, or explicit vs. implicit law, or rule of law vs. rule of man (vs. rule by machine).

The option you will not have, not for very long, is no law. If you ban hard you get soft, if you punish explicit you get implicit, if you defeat careful you get blunt, if you fight good you end up with bad. If rule of law is unworkable, you have two options left, which one is it going to be?

Without Chevron, and with certain people fighting tooth and nail against any attempt to do precise well-considered interventions and also the general failures of Congress, there is less room (as I understand it) for improvised ‘medium’ solutions, and the solution types we would all prefer seem more likely to be blocked.

Thus I fear by default Adam is right on this on the margin. That also means that those most vulnerable to government soft power have to tiptoe around such threats, and those less vulnerable have no idea how to comply and instead hope they don’t trigger the hammer, which is not the way to do things safely.

My default guess is that things do not change so much. Yes, it will be a mess in many ways, but all the talk of big disasters and opportunities will prove overblown. That is usually the safe default. As I understand the ruling, you can still delegate authority, the only difference is that Congress has to explicitly do that. Mostly I’d presume various workarounds mostly suffice.

Deb Raji disagrees and sees this as gutting our ability to respond because we were entirely dependent on rulemaking authority, and the flexibility to respond as circumstances change.

Balaji of course calls this ‘Chevron Dominance’ and says ‘technology is about to accelerate.’ It’s funny. He thinks ‘Congress did not give the SEC the authority to relegate crypto’ as if being on a blockchain should make you immune to existing laws. The SEC has authority over securities. You made new securities. That’s on you. But more generally, he is saying ‘regulators just got disarmed’ and that everyone’s now free to do what they want. ‘I can already feel the T-levels across tech increasing,’ he says.

As another example, Austen Allred has a thread saying this ‘may be the most impactful thing to happen to startups in a long time,’ full of some very choice words for Chevron and the SEC. At some point that counts as supreme restraint. And certainly not being told how to comply with the law is infuriating.

I notice a clear pattern. For some people, no matter what It might be, It is always A Big Deal. Any little movement changes everything. Miami bans lab-grown meat? RIP Miami. California says giant frontier models have to do paperwork? RIP startup ecosystem. And it works in the other direction, too, Chevron is gone so LFG. They talk about lots of other aspects of a business the same way.

Scott Adams explained back in 2016 why Trump talks this way, it exerts maximum leverage until and unless people properly adjust for it. Similarly, everyone in crypto is always super hyped about whatever it is, and how it is changing everything. Which it isn’t.

Justin Slaughter thinks this is a sea change. You won’t be able to extend your authority to new areas as they arise without Congress approving, an increasingly tough ask. And he also warns of the shift to enforcement actions.

Justin Slaughter: Last year, on vacation with a friend who is very against crypto & senior in government, I asked him why the SEC wouldn’t just do regulations on crypto instead of enforcement. He said “it’s much easier for this Supreme Court to strike down regulations than enforcement actions.”

In the short term, I suspect a lot of agencies will take the Court literally rather than seriously and try to shift quasi-regulatory efforts on novel topics like crypto and AI into enforcement actions. @tphillips has some very thoughtful ideas on this.

I think it probably won’t work because this Supreme Court is very hostile to administrative powers that aren’t explicitly delegated. They’re trying to cabin all novel approaches.

When everyone says ‘oh great, now they will have to tell us the rules or else let us build, we can do all sorts of cool startups now!’ I sincerely hope that it works that way. I fear that in practice it is the other way. For crypto in particular I think the SEC is on solid ground from a technical legal perspective, and people should not get overexcited.

Here is another illustration of the problem, from Matt Bruenig and Matthew Zeitlin:

Critical Bureaucracy Theory: Privately, re Chevron Deference. I’ve seen quite a few tech entrepreneurs say this:

Generic Tech Entrepreneur: I think the impact of this may be disproportionately significant for start-ups. There are trade-offs when seeking guidance on what are legal / regulatory requirements when doing tech or business model innovation from agencies versus courts, but in my experience as an entrepreneur, legal precedent usually provides much greater certainty than “what will regulators decide about this three years from now after we’ve sunk lots of VC and three years of our lives into the business?”.

When you have fewer than, say, several thousand employees, it’s almost impossible to get a regulator to tell you anything or provide any kind of safe harbor statement until Megacorp forces them to act — obviously usually in a way that benefits Megacorp.

Matthew Zeitlin: One thing that lots of tech people genuinely believe is that they should be able to get advisory opinions and thus safe harbor from regulators and even prosecutors on their products and business practices and that they can’t is a great offense against the rule of law.

Houziren: Lots of people in general believe that the government should enunciate what the law is, and that fact that you never know you’ve broken the law until you’re found guilty really is a great offense.

Matthew Zeitlin: yes i agree that many people can’t think more than one step ahead

Matt Bruenig: Even during Chevron, the process of promulgating a rule was so insane and got so little actual deference from courts that for an agency like the NLRB for instance, it made far more sense to just signal possible law changes and decide adjudications than clearly lay out the rules.

The NLRB spent multiple years ticking off all the boxes for creating a formal regulation defining what a joint employer is for the purposes of the NLRA only to have a conservative district court judge in Texas zap it immediately. Why bother!

Anyways, the same procedural tricks that are being used to make regulating impossible (ostensibly for conservative political goals) also generate counter-strategies that make legal certainty impossible (which people say is bad for business!)

Matthew Anderson: The IRS does this too; but they are also willing to issue advisory opinions.

I agree we should aspire to what the tech people want here. We should demand it, to the extent possible, that we be told what is legal and what is illegal.

That is not, alas, how our system works, or how it fully can work. The regulators are not there to decide in advance exactly what the rule is for you.

In particular, they are not there to help you tippy-toe up to the edge, figure out exactly how to pull off your regulatory arbitrage, and then stand there powerless to do anything because technically they said what you are doing was acceptable and you don’t have to play by the same rules as Megacorp. Or, alternatively, to give you an opinion, then you use that to sue them. Also no fun from their side.

The good news from that perspective is this sets off a bunch of lawsuits. Those lawsuits provide clarity. The bad news is that this discourages rule making in favor of vague indications and case by case policy. That is not what startups want.

Carl Shulman spends over four hours on 80,000 hours talking about the economy and national security after AGI, and it is only part 1. A lot of the content is similar to Carl’s talk with Dwarkesh Patel last year.

I continue to feel like Carl is spending a lot of time on, maybe not the wrong questions, but not the questions where I have uncertainty.

Yes, there is a ton of energy available and in some theoretical sense we could do all the things. Yes, replication can if done efficiently happen fast. Yes, AGI could solve robots and do all the things. We know all that. The vision is ‘if we have lots of super capable AIs that do things humans want and coordinate to do that in ways that are good for humans, we would have all the things and solve so many problems,’ and yeah, fine, we agree.

Indeed, the central theme of this podcast is ‘people have this objection, but actually if you look at the physical situation and logic behind it, that objection matters little or is rather dumb’ and indeed, Carl is basically always right about that, most of the objections people make are dumb. They are various forms of denying the premise in ways more basic than where Carl ignores the implications of the premise.

They first goes through six core objections to Carl’s vision.

  1. Why aren’t we seeing more economic growth today? Because we would not expect to until later, that is how exponentials work and the things that allow this rapid growth aren’t here yet.

  2. How could doubling times be so much shorter than has ever been true historically? Because the historic doubling times are the result of physical constraints that will not apply.

  3. Won’t we see declining returns to intelligence? No, we won’t, but also Carl points out that his model does not require it.

    1. Indeed, I would say his model feels impossible to me not because it is so out there, but because he is assuming normality where he shouldn’t, and this is one of the key places for that. It is a vision of AGI without ASI, and he correctly points out there would be a lot of economic growth, but also there would be ASI. If you are pointing out repeatedly ‘doesn’t sleep, intense motivation’ and so on to contrast with the humans, you are not wrong and maybe people need to hear that, but you are missing the point?

  4. Isn’t this an unrealistic amount of transformation of physical space? No, we’ve done it before and with AGI we would be able to do it again. Yes, some places might make that illegal, if so the action happens elsewhere. The places that refuse get left behind.

  5. Won’t we demand more safety and security? He basically says we might want it but good luck coordinating to get it in the face of how valuable this stuff is on various fronts including for military power. No one is going to forego the next industrial revolution and be worth worrying about after they do.

  6. Isn’t this all completely whack? Cool story, bro? No, not really, there are plenty of precedents, things not changing quickly would actually be the weird outcome. And it doesn’t matter how it sounds to you, previous tech revolutions sounded similar, what matters is what physically causes what.

So I indeed find those objections unconvincing. But the obvious seventh objection is missing: Won’t these AGIs very quickly have control over the future? Why would all this energy get spent in ways that benefit humans, even if you do ‘solve alignment’? And what makes you think you can solve that while charging forward?

I can’t get past this implicit (and often explicit) idea that something has to go actively wrong for things to end badly. The ‘risk of accidental trouble, things like a rogue AI takeover,’ instead of thinking that in a world transformed every few months where AIs do all the work and are more capable and efficient than us in every way us staying in charge seems pretty unlikely and weird and hard to pull off.

In the discussion of inequality and income, Carl says there will be tons of pressure from people to redistribute some of this vastly greater wealth, and plenty to go around, so there is no need to worry. Why would we assume this pressure impacts what happens? What is this ‘in democracies’? Why should we expect such things to long endure in these scenarios? Again, aren’t we assuming some very weirdly narrow range of AGI capabilities but not further capabilities for any of this to make sense?

The discussion of economists starts with Carl agreeing that ‘they say no way’ and yeah, they say that.

Then he goes over Baumol effect arguments, which are dumb because these AGIs can do all the things, and even if they can’t you can change the basket to work around the missing elements.

Or they deny robots can exist because robotics is unsolvable, which means they should not interrupt the people solving it, and also Carl points out so what, it would ultimately change little and not slow things down that much even if robots was indeed unsolvable because literal physical humans could be the robots with AIs directing them. And that’s largely good enough, because this whole scenario is actually being highly unimaginative.

What about input shortages especially for semiconductors? Carl answers historically rapid growth is common. I would add that with AGI help on this front too it would get a lot easier to go faster.

Carl points out that standard economic models actually very much do imply super rapid economic growth in these spots. Economists mostly refuse to admit this and instead construct these models where AI is only this narrow thing that does particular narrow tasks and make the assumptions that drive their absurd conclusions.

Won’t we be slow to hand over decision making to AIs? Carl points out that if the incentives are strong enough, we will not be that slow.

Why are economists dropping this ball so badly? They speculate about that, Carl points out some Econ 101 standard intuitions that stand in the way, and they are used to bold claims like this being wrong. And the economists expect everything to be gradual and ‘economic normal,’ and don’t get that this won’t hold.

They then spend an hour on the moral status of AIs. It is so weird to build up this whole model assuming the humans stay in charge, only then to notice that 99.999% of the intelligences in this world, that are more capable than humans, are not humans and may have moral standing, and then offhand say ‘well in these scenarios we have solved alignment and interpretability, so…’. And then they talk about these minds having open ended goals and wanting to survive and taking on risk and so on, and yes during this hour they notice the possibility of AI ‘domination.’

There is a part 2 coming, and it looks like it will address these issues a nonzero amount, but not obviously all that much.

I continue to find the Carl Shulman vision alienating, a weird kind of middle ground and way of thinking and doing math. Is it convincing to some people, as a kind of existence proof? I have no idea.

Bill Gates predicts computer interfaces will become agent driven, but far more importantly that ASI is coming and there is no way to slow it down. He sees scaling as only having ‘two more cranks,’ video data and synthetic data, but expects success via improved metacognition that is more humanlike.

Andrej Karpathy talks at UC Berkeley, similarly predicts Her-style interface.

Q&A with Geoffrey Hinton.

Dario Amodei and Elad Gil talk to Google Cloud Next. Seemed inessential.

Some troubling news.

Oliver Habryka: I am confident, on the basis of private information I can’t share, that Anthropic has asked employees to sign similar non-disparagement agreements that are covered by non-disclosure agreements as OpenAI did.

Or to put things into more plain terms:

I am confident that Anthropic has offered at least one employee significant financial incentive to promise to never say anything bad about Anthropic, or anything that might negatively affects its business, and to never tell anyone about their commitment to do so.

I am not aware of Anthropic doing anything like withholding vested equity the way OpenAI did, though I think the effect on discourse is similarly bad.

I of course think this is quite sad and a bad thing for a leading AI capability company to do, especially one that bills itself on being held accountable by its employees and that claims to prioritize safety in its plans.

At least one person in position to know has said no such agreement was ever offered to them, so this was at least not universal. We do not know how common it has been.

This came up during a Transfromer interview with Lawrence Lessig. Lessig is a strong advocate for open source in other contexts, but notices AI is different.

Lawrence Lessig: You basically have a bomb that you’re making available for free, and you don’t have any way to defuse it necessarily.

We ought to be anxious about how, in fact, [AI] could be deployed or used, especially when we don’t really understand how it could be misused.

It’s not inconsistent to recognise at some point, the risks here need to be handled in a different kind of way … The fact that we believe in GNU Linux doesn’t mean that we have to believe in every single risk being open to the world to exploit.

Shakeel Hashim: Lessig, who is now a professor at Harvard Law School and representing a group of OpenAI whistleblowers, dismissed comparisons to previous technologies, where access to program code is considered to have improved security and fostered innovation. “It’s just an obviously fallacious argument,” he said. “We didn’t do that with nuclear weapons: we didn’t say ‘the way to protect the world from nuclear annihilation is to give every country nuclear bombs.’”

A line attempted to be drawn to scale, Yudkowsky via Cameron of Dank EA Memes.

Remember that both sides of the line go out into the distance a very long way.

OpenAI offers a paper on using GPT-4 to find GPT-4’s mistakes.

They train the model to spot mistakes in code. It finds mistakes more efficiently than untrained GPT-4 and better than human evaluators. For now, a human-LLM combined team does better still by reducing false positives.

They partly used intentional tampering to introduce subtle bugs.

Our goal is to find a method that will apply to long-form and open-ended tasks for which we do not have a ground-truth reward function. One could simply train critique models on unmodified answers but that approach has at least the following issues:

• Preference rates are impacted by a number of stylistic factors and may over-estimate model performance.

• Contractors may struggle to validate the correctness of free-form critiques if they make obscure claims.

• Contractors may struggle to spot important issues that critiques miss.

• Many answers will not contain severe issues, reducing the value of the data for improving critiques.

In addition to RLHF they use a technique called Force Sampling Beam Search (FSBS).

The critic also performed ‘out of sample’ on non-code examples, where it often managed to spot issues with samples previously rated by humans as flawless, sufficiently important that the humans no longer considered the samples flawless.

The conclusion is worth quoting:

Large language models have already passed the point at which typical humans can consistently evaluate their output without help. This has been evident since demonstrations of their strong performance on PhD-level science questions, among other impressive feats [25]. The need for scalable oversight, broadly construed as methods that can help humans to correctly evaluate model output, is stronger than ever.

Whether or not RLHF maintains its dominant status as the primary means by which LLMs are post-trained into useful assistants, we will still need to answer the question of whether particular model outputs are trustworthy. Here we take a very direct approach: training models that help humans to evaluate models.

These LLM critics now succeed in catching bugs in real-world data, and even accessible LLM baselines like ChatGPT have significant potential to assist human annotators.

From this point on the intelligence of LLMs and LLM critics will only continue to improve. Human intelligence will not.

It is therefore essential to find scalable methods that ensure that we reward the right behaviors in our AI systems even as they become much smarter than us. We find LLM critics to be a promising start.

Jan Leike, who contributed to this paper while still at OpenAI, offers thoughts here.

As a practical matter this all seems neat and helpful. The average accuracy of the evaluations will go up relative to human evaluations.

Code is easy mode, since the answer of whether it works is relatively objective. Value here is not so fragile. It is a good place to start. It also masks the dangers.

My concern is that this creates great temptation to rely on AI evaluations of AI, and to iterate repeatedly on those evaluations. It risks enshrining systematic correlated error, and amplifying those issues over time as the process feeds back upon itself. There are any number of ways that can go horribly wrong, starting with supercharged versions of all the usual Goodhart’s Law problems.

The average scoring, including the average human spot check, will look good for as long as we can understand what is going on, if we execute on this reasonably. Performance will genuinely be better at first. That will add to the temptation. Then the results will increasingly diverge.

Here is another example of going down a similar path.

AK: Self-Play Preference Optimization for Language Model Alignment

Traditional reinforcement learning from human feedback (RLHF) approaches relying on parametric models like the Bradley-Terry model fall short in capturing the intransitivity and irrationality in human preferences.

Recent advancements suggest that directly working with preference probabilities can yield a more accurate reflection of human preferences, enabling more flexible and accurate language model alignment. In this paper, we propose a self-play-based method for language.

Davidad: I think this is the new SotA prosaic-LLM-alignment post-training algorithm, besting DPO.

I do like the idea of working with preference probabilities. I worry about working self-play into the picture, as it seems likely to exacerbate our Goodhart’s Law issues.

A wrong but useful model of AI risk is attempted.

Joshua Achiam: AI risk increases smoothly over time, in concert with capabilities, rather than discontinuously. But at some point the world will pass a critical threshold where we would lose a war against an AI adversary if such a war arose and the human side were unaided/unaugmented.

I am a little surprised, in general, at how underdeveloped the thinking is around what this conflict might look like if it happened. This seems like it should be at the root of a lot of threat modeling.

Several distinct things are usefully wrong here.

A few thoughts.

Our estimate of the path of future AI existential risk over time is changing like any good Bayesian estimate. Some events or information make the risk go up, some make it go down. Some insights make our estimate go up or down by revealing what was already true, others represent choices made by people.

Eventually, yes, the risk in the short term (~1 year or less let’s say), either of the event happening or us passing a ‘point of no return’ where in practice we are incapable of responding, starts to go up. From an outside view that may look steady, from an inside view it probably involves one or more large step changes as well, on key private and public decisions or on passage of time to critical points.

Top ten obvious examples after five minutes of thinking:

  1. The decision to continue training, continue testing or releasing a new model.

  2. A rogue actor decides to intentionally train and deploy an AI in a particular way.

  3. A key secret, including model weights, is stolen and falls into the wrong hands.

  4. The decision whether to institute key international cooperation or regulation.

  5. A battle for control of a key institution, including both labs and governments

  6. A catastrophic event or other warning sign that forces a response.

  7. A war or other crisis even if caused by humans.

  8. Discovery of a key new idea in capabilities or alignment.

  9. An AGI/ASI gains the capability to successfully take control.

  10. AGI/ASI becomes too central to our economy and discourse to dare act against it.

Some of these could be gradual, but many are likely or inherently sudden.

In particular, tie in the ability to take control versus the risk of it happening.

The traditional Yudkowsky or sharp left turn scenario is that these are the same thing. The highly intelligent and capable AI is going to attempt to take control if and only if it is confident that attempt would succeed at letting it fulfill its objectives (or it might well work and the risks of waiting are greater). The logic is obvious, and humans do their best to follow that logic as well.

Then there is the idea of a battle between ‘an AI adversary’ and ‘the human side.’

  1. We hopefully have learned by now that there is no human side. There are only a bunch of humans, doing things. Their ability to cooperate and coordinate is sufficiently limited that our candidates in 2024 are Biden and Trump and we continue to race to AGI.

  2. In the scenario in question, if the fight was somehow close and non-trivial, the AGI would presumably use various techniques to ensure there very much was not a human side, and many or most people did not appreciate what was happening, and many actively backed the AI.

  3. The human side being ‘unaided/unaugmented’ is similarly bizarre. If the AI is sufficiently strong that it can take over all the systems that might aid or augment us, then I presume it is already over.

Why is this conflict not gamed out more?

Because there are mostly two groups of people here.

  1. People who understand, as Joshua does, that at some point the AI will win.

  2. People who will come up with any rationalizations as needed to deny this.

    They will come up with various increasingly absurd excuses and hopium as needed.

When someone in group #1 talks to someone in group #2, the goal is to convince people to accept the obvious. So you don’t game out exactly how the conflict works in practice or what the threshold is. You instead see what their absurd excuse or hopium is, and shoot it down and overwhelm it, and then they adjust, and you do it again. Occasionally this works and they become enlightened. When that happens, you are happy, great talk, but you are not closer to figuring out where the thresholds are.

When people in group #1 talk to each other about this, they still have radically different assumptions about among other things which AIs are against you and threat vectors and what scenarios might look like and how various things would work or people would react, and also the real scenarios involve effectively smarter things than you and also the details depend on unknown things about the future path of capabilities and conditions. So it is still super hard to make progress. And responding to a particular scenario on the margin based on how you think the battle would go is unlikely to turn losses into wins.

Mostly my answer is ‘yes, if capabilities do not stall we will effectively pass this point.’

From last week in audio: Aravind Srinivas, CEO of Perplexity, played a jarring mix of great founder and idiot disaster monkey on Lex Fridman. The parts where he describes the practical business of Perplexity are great, assuming he is not making things up. Then he will speculate about a future full of powerful AI agents doing everything, and say ‘I am not worried about AIs taking over’ as a throwaway line and get back to talking about other things, or say that open sourcing is the way to go because most people won’t have enough compute to do anything dangerous with the models.

I suspect that when Aravind says not worried, he and many others mean that literally.

As in, what me worry?

Or as in the way most people find a way to not worry about death.

It is not that Aravind thinks this will not happen. We all know that the planetary death rate is holding steady at 100%, but what is the point of going all existential angst about it? If AI is likely to get us all killed somewhat faster this round, well, that’s unfortunate but in the meantime let’s go build one of those great companies and worry about it later.

He then combines this with failure to feel the AGI. He is super excited for exactly the AIs that he expects, which will be able to be creative like Einstein, do tons of that thinking without humans present and come back to you, act as your agents, and do all the other cool things, exactly enough to be maximally awesome for humans, but not so much that humans have to worry about loss of control.

How is that possible? Is there even a narrow window of theoretical capability where you can have those abilities without the dangers? I mean, no, obviously there isn’t, but you can sort of pretend that there is and then also assume we will stabilize in exactly that part of the curve despite then discovering all of physics and so on.

The good news is that running Perplexity is almost entirely about being a great founder, so in practice what he does is mostly good. The ‘answer engine’ idea is great, and occasionally I find it the right tool for the right job although mostly I end up at either the Google Search or Claude Sonnet ends of the spectrum.

I do appreciate that ‘I don’t believe in ASI’ has moved from implied but unnoticed subtext to very clear text.

Ab Homine Deus: Saying “I don’t believe in ASI” is just the most insane cope. Let’s say Einstein-level intelligence truly is some sort of universal intelligence speed limit. What do you think 1000s of Einstein’s thinking together thousands of times faster than humanly possible looks like?

The longest kiss.

One missing word makes all the difference.

Millions of OnlyFans paywalls make it hard to detect child sex abuse, cops say

Millions of OnlyFans paywalls make it hard to detect child sex abuse, cops say

OnlyFans’ paywalls make it hard for police to detect child sexual abuse materials (CSAM) on the platform, Reuters reported—especially new CSAM that can be harder to uncover online.

Because each OnlyFans creator posts their content behind their own paywall, five specialists in online child sexual abuse told Reuters that it’s hard to independently verify just how much CSAM is posted. Cops would seemingly need to subscribe to each account to monitor the entire platform, one expert who aids in police CSAM investigations, Trey Amick, suggested to Reuters.

OnlyFans claims that the amount of CSAM on its platform is extremely low. Out of 3.2 million accounts sharing “hundreds of millions of posts,” OnlyFans only removed 347 posts as suspected CSAM in 2023. Each post was voluntarily reported to the CyberTipline of the National Center for Missing and Exploited Children (NCMEC), which OnlyFans told Reuters has “full access” to monitor content on the platform.

However, that intensified monitoring seems to have only just begun. NCMEC just got access to OnlyFans in late 2023, the child safety group told Reuters. And NCMEC seemingly can’t scan the entire platform at once, telling Reuters that its access was “limited” exclusively “to OnlyFans accounts reported to its CyberTipline or connected to a missing child case.”

Similarly, OnlyFans told Reuters that police do not have to subscribe to investigate a creator’s posts, but the platform only grants free access to accounts when there’s an active investigation. That means once police suspect that CSAM is being exchanged on an account, they get “full access” to review “account details, content, and direct messages,” Reuters reported.

But that access doesn’t aid police hoping to uncover CSAM shared on accounts not yet flagged for investigation. That’s a problem, a Reuters investigation found, because it’s easy for creators to make a new account, where bad actors can mask their identities to avoid OnlyFans’ “controls meant to hold account holders responsible for their own content,” one detective, Edward Scoggins, told Reuters.

Evading OnlyFans’ CSAM detection seems easy

OnlyFans told Reuters that “would-be creators must provide at least nine pieces of personally identifying information and documents, including bank details, a selfie while holding a government photo ID, and—in the United States—a Social Security number.”

“All this is verified by human judgment and age-estimation technology that analyzes the selfie,” OnlyFans told Reuters. On OnlyFans’ site, the platform further explained that “we continuously scan our platform to prevent the posting of CSAM. All our content moderators are trained to identify and swiftly report any suspected CSAM.”

However, Reuters found that none of these controls worked 100 percent of the time to stop bad actors from sharing CSAM. And the same seemingly holds true for some minors motivated to post their own explicit content. One girl told Reuters that she evaded age verification first by using an adult’s driver’s license to sign up, then by taking over an account of an adult user.

An OnlyFans spokesperson told Ars that low amounts of CSAM reported to NCMEC is a “testament to the rigorous safety controls OnlyFans has in place.”

OnlyFans is proud of the work we do to aggressively target, report, and support the investigations and prosecutions of anyone who seeks to abuse our platform in this way,” OnlyFans’ spokesperson told Ars. “Unlike many other platforms, the lack of anonymity and absence of end-to-end encryption on OnlyFans means that reports are actionable by law enforcement and prosecutors.”

AI trains on kids’ photos even when parents use strict privacy settings

“Outrageous” —

Even unlisted YouTube videos are used to train AI, watchdog warns.

AI trains on kids’ photos even when parents use strict privacy settings

Human Rights Watch (HRW) continues to reveal how photos of real children casually posted online years ago are being used to train AI models powering image generators—even when platforms prohibit scraping and families use strict privacy settings.

Last month, HRW researcher Hye Jung Han found 170 photos of Brazilian kids that were linked in LAION-5B, a popular AI dataset built from Common Crawl snapshots of the public web. Now, she has released a second report, flagging 190 photos of children from all of Australia’s states and territories, including indigenous children who may be particularly vulnerable to harms.

These photos are linked in the dataset “without the knowledge or consent of the children or their families.” They span the entirety of childhood, making it possible for AI image generators to generate realistic deepfakes of real Australian children, Han’s report said. Perhaps even more concerning, the URLs in the dataset sometimes reveal identifying information about children, including their names and locations where photos were shot, making it easy to track down children whose images might not otherwise be discoverable online.

That puts children in danger of privacy and safety risks, Han said, and some parents thinking they’ve protected their kids’ privacy online may not realize that these risks exist.

From a single link to one photo that showed “two boys, ages 3 and 4, grinning from ear to ear as they hold paintbrushes in front of a colorful mural,” Han could trace “both children’s full names and ages, and the name of the preschool they attend in Perth, in Western Australia.” And perhaps most disturbingly, “information about these children does not appear to exist anywhere else on the Internet”—suggesting that families were particularly cautious in shielding these boys’ identities online.

Stricter privacy settings were used in another image that Han found linked in the dataset. The photo showed “a close-up of two boys making funny faces, captured from a video posted on YouTube of teenagers celebrating” during the week after their final exams, Han reported. Whoever posted that YouTube video adjusted privacy settings so that it would be “unlisted” and would not appear in searches.

Only someone with a link to the video was supposed to have access, but that didn’t stop Common Crawl from archiving the image, nor did YouTube policies prohibiting AI scraping or harvesting of identifying information.

Reached for comment, YouTube’s spokesperson, Jack Malon, told Ars that YouTube has “been clear that the unauthorized scraping of YouTube content is a violation of our Terms of Service, and we continue to take action against this type of abuse.” But Han worries that even if YouTube did join efforts to remove images of children from the dataset, the damage has been done, since AI tools have already trained on them. That’s why—even more than parents need tech companies to up their game blocking AI training—kids need regulators to intervene and stop training before it happens, Han’s report said.

Han’s report comes a month before Australia is expected to release a reformed draft of the country’s Privacy Act. Those reforms include a draft of Australia’s first child data protection law, known as the Children’s Online Privacy Code, but Han told Ars that even people involved in long-running discussions about reforms aren’t “actually sure how much the government is going to announce in August.”

“Children in Australia are waiting with bated breath to see if the government will adopt protections for them,” Han said, emphasizing in her report that “children should not have to live in fear that their photos might be stolen and weaponized against them.”

AI uniquely harms Australian kids

To hunt down the photos of Australian kids, Han “reviewed fewer than 0.0001 percent of the 5.85 billion images and captions contained in the data set.” Because her sample was so small, Han expects that her findings represent a significant undercount of how many children could be impacted by the AI scraping.

“It’s astonishing that out of a random sample size of about 5,000 photos, I immediately fell into 190 photos of Australian children,” Han told Ars. “You would expect that there would be more photos of cats than there are personal photos of children,” since LAION-5B is a “reflection of the entire Internet.”

LAION is working with HRW to remove links to all the images flagged, but cleaning up the dataset does not seem to be a fast process. Han told Ars that based on her most recent exchange with the German nonprofit, LAION had not yet removed links to photos of Brazilian kids that she reported a month ago.

LAION declined Ars’ request for comment.

In June, LAION’s spokesperson, Nathan Tyler, told Ars that, “as a nonprofit, volunteer organization,” LAION is committed to doing its part to help with the “larger and very concerning issue” of misuse of children’s data online. But removing links from the LAION-5B dataset does not remove the images online, Tyler noted, where they can still be referenced and used in other AI datasets, particularly those relying on Common Crawl. And Han pointed out that removing the links from the dataset doesn’t change AI models that have already trained on them.

“Current AI models cannot forget data they were trained on, even if the data was later removed from the training data set,” Han’s report said.

Kids whose images are used to train AI models are exposed to a variety of harms, Han reported, including a risk that image generators could more convincingly create harmful or explicit deepfakes. In Australia last month, “about 50 girls from Melbourne reported that photos from their social media profiles were taken and manipulated using AI to create sexually explicit deepfakes of them, which were then circulated online,” Han reported.

For First Nations children—”including those identified in captions as being from the Anangu, Arrernte, Pitjantjatjara, Pintupi, Tiwi, and Warlpiri peoples”—the inclusion of links to photos threatens unique harms. Because culturally, First Nations peoples “restrict the reproduction of photos of deceased people during periods of mourning,” Han said the AI training could perpetuate harms by making it harder to control when images are reproduced.

Once an AI model trains on the images, there are other obvious privacy risks, including a concern that AI models are “notorious for leaking private information,” Han said. Guardrails added to image generators do not always prevent these leaks, with some tools “repeatedly broken,” Han reported.

LAION recommends that, if troubled by the privacy risks, parents remove images of kids online as the most effective way to prevent abuse. But Han told Ars that’s “not just unrealistic, but frankly, outrageous.”

“The answer is not to call for children and parents to remove wonderful photos of kids online,” Han said. “The call should be [for] some sort of legal protections for these photos, so that kids don’t have to always wonder if their selfie is going to be abused.”

Google’s greenhouse gas emissions jump 48% in five years

computationally intensive means energy intensive —

Google’s 2030 “Net zero” target looks increasingly doubtful as AI use soars.

Cooling pipes at a Google data center in Douglas County, Georgia.

Cooling pipes at a Google data center in Douglas County, Georgia.

Google’s greenhouse gas emissions have surged 48 percent in the past five years due to the expansion of its data centers that underpin artificial intelligence systems, leaving its commitment to get to “net zero” by 2030 in doubt.

The Silicon Valley company’s pollution amounted to 14.3 million tonnes of carbon equivalent in 2023, a 48 percent increase from its 2019 baseline and a 13 percent rise since last year, Google said in its annual environmental report on Tuesday.

Google said the jump highlighted “the challenge of reducing emissions” at the same time as it invests in the build-out of large language models and their associated applications and infrastructure, admitting that “the future environmental impact of AI” was “complex and difficult to predict.”

Chief Sustainability Officer Kate Brandt said the company remained committed to the 2030 target but stressed the “extremely ambitious” nature of the goal.

“We do still expect our emissions to continue to rise before dropping towards our goal,” said Brandt.

She added that Google was “working very hard” on reducing its emissions, including by signing deals for clean energy. There was also a “tremendous opportunity for climate solutions that are enabled by AI,” said Brandt.

As Big Tech giants including Google, Amazon, and Microsoft have outlined plans to invest tens of billions of dollars into AI, climate experts have raised concerns about the environmental impacts of the power-intensive tools and systems.

In May, Microsoft admitted that its emissions had risen by almost a third since 2020, in large part due to the construction of data centers. However, Microsoft co-founder Bill Gates last week also argued that AI would help propel climate solutions.

Meanwhile, energy generation and transmission constraints are already posing a challenge for the companies seeking to build out the new technology. Analysts at Bernstein said in June that AI would “double the rate of US electricity demand growth and total consumption could outstrip current supply in the next two years.”

In Tuesday’s report, Google said its 2023 energy-related emissions—which come primarily from data center electricity consumption—rose 37 percent year on year and overall represented a quarter of its total greenhouse gas emissions.

Google’s supply chain emissions—its largest chunk, representing 75 percent of its total emissions—also rose 8 percent. Google said they would “continue to rise in the near term” as a result in part of the build-out of the infrastructure needed to run AI systems.

Google has pledged to achieve net zero across its direct and indirect greenhouse gas emissions by 2030 and to run on carbon-free energy during every hour of every day within each grid it operates by the same date.

However, the company warned in Tuesday’s report that the “termination” of some clean energy projects during 2023 had pushed down the amount of renewables it had access to.

Meanwhile, the company’s data center electricity consumption had “outpaced” Google’s ability to bring more clean power projects online in the US and Asia-Pacific regions.

Google’s data center electricity consumption increased 17 percent in 2023, and amounted to approximately 7-10 percent of global data center electricity consumption, the company estimated. Its data centers also consumed 17 percent more water in 2023 than during the previous year, Google said.

Biden rushes to avert labor shortage with CHIPS act funding for workers

Less than one month to apply —

To dodge labor shortage, US finally aims CHIPS Act funding at training workers.

US President Joe Biden (C) speaks during a tour of the TSMC Semiconductor Manufacturing Facility in Phoenix, Arizona, on December 6, 2022.

Enlarge / US President Joe Biden (C) speaks during a tour of the TSMC Semiconductor Manufacturing Facility in Phoenix, Arizona, on December 6, 2022.

In the hopes of dodging a significant projected worker shortage in the next few years, the Biden administration will finally start funding workforce development projects to support America’s ambitions to become the world’s leading chipmaker through historic CHIPS and Science Act investments.

The Workforce Partner Alliance (WFPA) will be established through the CHIPS Act’s first round of funding focused on workers, officials confirmed in a press release. The program is designed to “focus on closing workforce and skills gaps in the US for researchers, engineers, and technicians across semiconductor design, manufacturing, and production,” a program requirements page said.

Bloomberg reported that the US risks a technician shortage reaching 90,000 by 2030. This differs slightly from Natcast’s forecast, which found that out of “238,000 jobs the industry is projected to create by 2030,” the semiconductor industry “will be unable to fill more than 67,000.”

Whatever the industry demand will actually be, with a projected tens of thousands of jobs needing to be filled just as the country is hoping to produce more chips than ever, the Biden administration is hoping to quickly train enough workers to fill openings for “researchers, engineers, and technicians across semiconductor design, manufacturing, and production,” a WFPA site said.

To do this, a “wide range of workforce solution providers” are encouraged to submit “high-impact” WFPA project proposals that can be completed within two years, with total budgets of between $500,000 and $2 million per award, the press release said.

Examples of “evidence-based workforce development strategies and methodologies that may be considered for this program” include registered apprenticeship and pre-apprenticeship programs, colleges or universities offering semiconductor industry-relevant degrees, programs combining on-the-job training with effective education or mentorship, and “experiential learning opportunities such as co-ops, externships, internships, or capstone projects.” While programs supporting construction activities will not be considered, programs designed to “reduce barriers” to entry in the semiconductor industry can use funding to support workers’ training, such as for providing childcare or transportation for workers.

“Making investments in the US semiconductor workforce is an opportunity to serve underserved communities, to connect individuals to good-paying sustainable jobs across the country, and to develop a robust workforce ecosystem that supports an industry essential to the national and economic security of the US,” Natcast said.

Between four to 10 projects will be selected, providing opportunities for “established programs with a track record of success seeking to scale,” as well as for newer programs “that meet a previously unaddressed need, opportunity, or theory of change” to be launched or substantially expanded.

The deadline to apply for funding is July 26, which gives applicants less than one month to get their proposals together. Applicants must have a presence in the US but can include for-profit organizations, accredited education institutions, training programs, state and local government agencies, and nonprofit organizations, Natcast’s eligibility requirements said.

Natcast—the nonprofit entity created to operate the National Semiconductor Technology Center Consortium—will manage the WFPA. An FAQ will be provided soon, Natcast said, but in the meantime, the agency is giving a brief window to submit questions about the program. Curious applicants can send questions to wfpa2024@natcast.org until 11: 59 pm ET on July 9.

Awardees will be notified by early fall, Natcast said.

Planning the future of US chip workforce

In Natcast’s press release, Deirdre Hanford, Natcast’s CEO, said that the WFPA will “accelerate progress in the US semiconductor industry by tackling its most critical challenges, including the need for a highly skilled workforce that can meet the evolving demands of the industry.”

And the senior manager of Natcast’s workforce development programs, Michael Barnes, said that the WFPA will be critical to accelerating the industry’s growth in the US.

“It is imperative that we develop a domestic semiconductor workforce ecosystem that can support the industry’s anticipated growth and strengthen American national security, economic prosperity, and global competitiveness,” Barnes said.

Alzheimer’s scientist indicted for allegedly falsifying data in $16M scheme

The work underpinned an Alzheimer’s drug by Cassava, now in a Phase III trial.

Alzheimer’s scientist indicted for allegedly falsifying data in $16M scheme

A federal grand jury has indicted an embattled Alzheimer’s researcher for allegedly falsifying data to fraudulently obtain $16 million in federal research funding from the National Institutes of Health for the development of a controversial Alzheimer’s drug and diagnostic test.

Hoau-Yan Wang, 67, a medical professor at the City University of New York, was a paid collaborator with the Austin, Texas-based pharmaceutical company Cassava Sciences. Wang’s research and publications provided scientific underpinnings for Cassava’s Alzheimer’s treatment, Simufilam, which is now in Phase III trials.

Simufilam is a small-molecule drug that Cassava claims can restore the structure and function of a scaffolding protein in the brain of people with Alzheimer’s, leading to slowed cognitive decline. But outside researchers have long expressed doubts and concerns about the research.

In 2023, Science magazine obtained a 50-page report from an internal investigation at CUNY that looked into 31 misconduct allegations made against Wang in 2021. According to the report, the investigating committee “found evidence highly suggestive of deliberate scientific misconduct by Wang for 14 of the 31 allegations,” the report states. The allegations largely centered around doctored and fabricated images from Western blotting, an analytical technique used to separate and detect proteins. However, the committee couldn’t conclusively prove the images were falsified “due to the failure of Dr. Wang to provide underlying, original data or research records and the low quality of the published images that had to be examined in their place.”

In all, the investigation “revealed long-standing and egregious misconduct in data management and record keeping by Dr. Wang,” and concluded that “the integrity of Dr. Wang’s work remains highly questionable.” The committee also concluded that Cassava’s lead scientist on its Alzheimer’s disease program, Lindsay Burns, who was a frequent co-author with Wang, also likely bears some responsibility for the misconduct.

In March 2022, five of Wang’s articles published in the journal PLOS One were retracted over integrity concerns with images in the papers. Other papers by Wang have also been retracted or had statements of concern attached to them. Further, in September 2022, the Food and Drug Administration conducted an inspection of the analytical work and techniques used by Wang to analyze blood and cerebrospinal fluid from patients in a simufilam trial. The investigation found a slew of egregious problems, which were laid out in a “damning” report obtained by Science.

In the indictment last week, federal authorities were explicit about the allegations, claiming that Wang falsified the results of his scientific research to NIH “by, among other things, manipulating data and images of Western blots to artificially add bands [which represent proteins], subtract bands, and change their relative thickness and/or darkness, and then drawing conclusions” based on those false results.

Wang is charged with one count of major fraud against the United States, two counts of wire fraud, and one count of false statements. If convicted, he faces a maximum penalty of 10 years in prison for the major fraud charge, 20 years in prison for each count of wire fraud, and five years in prison for the count of false statements, the Department of Justice said in an announcement.

In a statement posted to its website, Cassava acknowledged Wang’s indictment, calling him a “former” scientific adviser. The company also said that the grants central to the indictment were “related to the early development phases of the Company’s drug candidate and diagnostic test and how these were intended to work.” However, Cassava said that Wang “had no involvement in the Company’s Phase 3 clinical trials of simufilam.”

Those ongoing trials, which some have called to be halted, are estimated to include over 1,800 patients across several countries.

The telltale words that could identify generative AI text

Delving deep —

New paper counts “excess words” that started appearing more often in the post-LLM era.

Thus far, even AI companies have had trouble coming up with tools that can reliably detect when a piece of writing was generated using a large language model. Now, a group of researchers has established a novel method for estimating LLM usage across a large set of scientific writing by measuring which “excess words” started showing up much more frequently during the LLM era (i.e., 2023 and 2024). The results “suggest that at least 10% of 2024 abstracts were processed with LLMs,” according to the researchers.

In a pre-print paper posted earlier this month, four researchers from Germany’s University of Tubingen and Northwestern University said they were inspired by studies that measured the impact of the COVID-19 pandemic by looking at excess deaths compared to the recent past. By taking a similar look at “excess word usage” after LLM writing tools became widely available in late 2022, the researchers found that “the appearance of LLMs led to an abrupt increase in the frequency of certain style words” that was “unprecedented in both quality and quantity.”

Delving in

To measure these vocabulary changes, the researchers analyzed 14 million paper abstracts published on PubMed between 2010 and 2024, tracking the relative frequency of each word as it appeared across each year. They then compared the expected frequency of those words (based on the pre-2023 trendline) to the actual frequency of those words in abstracts from 2023 and 2024, when LLMs were in widespread use.

The results found a number of words that were extremely uncommon in these scientific abstracts before 2023 that suddenly surged in popularity after LLMs were introduced. The word “delves,” for instance, shows up in 25 times as many 2024 papers as the pre-LLM trend would expect; words like “showcasing” and “underscores” increased in usage by nine times as well. Other previously common words became notably more common in post-LLM abstracts: the frequency of “potential” increased 4.1 percentage points; “findings” by 2.7 percentage points; and “crucial” by 2.6 percentage points, for instance.

Some examples of words that saw their use increase (or decrease) substantially after LLMs were introduced (bottom three words shown for comparison).

Enlarge / Some examples of words that saw their use increase (or decrease) substantially after LLMs were introduced (bottom three words shown for comparison).

These kinds of changes in word use could happen independently of LLM usage, of course—the natural evolution of language means words sometimes go in and out of style. However, the researchers found that, in the pre-LLM era, such massive and sudden year-over-year increases were only seen for words related to major world health events: “ebola” in 2015; “zika” in 2017; and words like “coronavirus,” “lockdown” and “pandemic” in the 2020 to 2022 period.

In the post-LLM period, though, the researchers found hundreds of words with sudden, pronounced increases in scientific usage that had no common link to world events. In fact, while the excess words during the COVID pandemic were overwhelmingly nouns, the researchers found that the words with a post-LLM frequency bump were overwhelmingly “style words” like verbs, adjectives, and adverbs (a small sampling: “across, additionally, comprehensive, crucial, enhancing, exhibited, insights, notably, particularly, within”).

This isn’t a completely new finding—the increased prevalence of “delve” in scientific papers has been widely noted in the recent past, for instance. But previous studies generally relied on comparisons with “ground truth” human writing samples or lists of pre-defined LLM markers obtained from outside the study. Here, the pre-2023 set of abstracts acts as its own effective control group to show how vocabulary choice has changed overall in the post-LLM era.

An intricate interplay

By highlighting hundreds of so-called “marker words” that became significantly more common in the post-LLM era, the telltale signs of LLM use can sometimes be easy to pick out. Take this example abstract line called out by the researchers, with the marker words highlighted: “A comprehensive grasp of the intricate interplay between […] and […] is pivotal for effective therapeutic strategies.”

After doing some statistical measures of marker word appearance across individual papers, the researchers estimate that at least 10 percent of the post-2022 papers in the PubMed corpus were written with at least some LLM assistance. The number could be even higher, the researchers say, because their set could be missing LLM-assisted abstracts that don’t include any of the marker words they identified.

Before 2023, it took a major world event like the coronavirus pandemic to see large jumps in word usage like this.

Enlarge / Before 2023, it took a major world event like the coronavirus pandemic to see large jumps in word usage like this.

Those measured percentages can vary a lot across different subsets of papers, too. The researchers found that papers authored in countries like China, South Korea, and Taiwan showed LLM marker words 15 percent of the time, suggesting “LLMs might… help non-natives with editing English texts, which could justify their extensive use.” On the other hand, the researchers offer that native English speakers “may [just] be better at noticing and actively removing unnatural style words from LLM outputs,” thus hiding their LLM usage from this kind of analysis.

Detecting LLM use is important, the researchers note, because “LLMs are infamous for making up references, providing inaccurate summaries, and making false claims that sound authoritative and convincing.” But as knowledge of LLMs’ telltale marker words starts to spread, human editors may get better at taking those words out of generated text before it’s shared with the world.

Who knows, maybe future large language models will do this kind of frequency analysis themselves, lowering the weight of marker words to better mask their outputs as human-like. Before long, we may need to call in some Blade Runners to pick out the generative AI text hiding in our midst.

In a vast stretch of the Sonoran Desert, between the towns of San Luis Río Colorado and Sonoyta in northern Mexico, sits a modest building of cement, galvanized sheet metal, and wood—the only stop along 125 miles of inhospitable landscape dominated by thorny ocotillo shrubs and towering saguaro cactuses up to 50 feet high. It’s a fonda—a small restaurant—called La Liebre del Desierto (The Desert Hare), and for more than 20 years, owner Elsa Ortiz Ramos has welcomed and nourished weary travelers taking a break from the adjacent highway that runs through the arid Pinacate and Grand Desierto de Altar Biosphere Reserve.

But the dedication and care of this petite woman go beyond her simple menu. Every two weeks, she pays out of pocket for a 5,000-gallon tank of water to distribute to a network of water troughs strategically placed in the area. By doing so, she relieves the thirst of bighorn sheep, ocelots, pronghorn, coyotes, deer, and even bats that have been deprived of access to their natural water sources.

“The crows come to the house and scream to warn us that there is no more water … it’s our alarm,” says Ortiz Ramos in her distinct northern Mexico accent. Her words sound straight from an Aesop’s fable, but they take on stark realism in this spot. Covering large parts of Arizona, California, and the Mexican states of Baja California and Sonora, the Sonoran Desert—along with the Lut Desert in Iran—was cataloged in 2023 as having the hottest surface temperature on the planet, at 80.8° Celsius (177° Fahrenheit).

Through narrow steel bollards 3.5 inches apart, I observe lush vegetation surrounding the Quitobaquito spring on the other side of the border. “This vital source supplies both humans and animals over an area of more than 1 million hectares,” Federico Godínez Leal, an agronomist from the University of Guadalajara, explains to me. But now this crucial water source is restricted to the US side due to the construction of the border wall, and I have come with him here to understand the consequences. Godínez Leal and his team have been documenting the stark difference between each side: Their poignant photographs show skeletons of wild boar, deer, and bighorn sheep lying on Mexican soil.

Between 2017 and 2021, the US government installed more than 450 miles of border barriers—steel structures between 18 and 29 feet high, spaced less than 4 inches apart—in the western end of the more than 1,900 miles of border between Mexico and the United States, stretching from the Pacific Ocean to the Gulf of Mexico. Of these 450 miles, 81 percent were replacements of existing vehicular or pedestrian barriers—but which, due to their design, allowed some passage of animals across the border. The rest were new barriers.

Before its construction, scientists on both sides of the border had warned about the impact that the wall could have on the animals of the area, and they are now working to understand the consequences. In turn, villagers in some spots on the Mexican side of the border have organized to try to alleviate the thirst of many animals that have been left without access to water.

DNA from mammoth remains reveals the history of the last surviving population

Sole survivors —

The mammoths of Wrangel Island purged a lot of harmful mutations before dying off.

A small group of woolly mammoths became trapped on Wrangel Island around 10,000 years ago when rising sea levels separated the island from mainland Siberia. Small, isolated populations of animals lead to inbreeding and genetic defects, and it has long been thought that the Wrangel Island mammoths ultimately succumbed to this problem about 4,000 years ago.

A paper in Cell on Thursday, however, compared 50,000 years of genomes from mainland and isolated Wrangel Island mammoths and found that this was not the case. What the authors of the paper discovered not only challenges our understanding of this isolated group of mammoths and the evolution of small populations, it also has important implications for conservation efforts today.

A severe bottleneck

It’s the culmination of years of genetic sequencing by members of the international team behind this new paper. They studied 21 mammoth genomes—13 of which were newly sequenced by lead author Marianne Dehasque; others had been sequenced years prior by co-authors Patrícia Pečnerová, Foteini Kanellidou, and Héloïse Muller. The genomes were obtained from Siberian woolly mammoths (Mammuthus primigenius), both from the mainland and the island before and after it became isolated. The oldest genome was from a female Siberian mammoth who died about 52,300 years ago. The youngest were from Wrangel Island male mammoths who perished right around the time the last of these mammoths died out (one of them died just 4,333 years ago).

It’s a remarkable and revealing time span: The sample included mammoths from a population that started out large and genetically healthy, went through isolation, and eventually went extinct.

Mammoths, the team noted in their paper, experienced a “climatically turbulent period,” particularly during an episode of rapid warming called the Bølling-Allerød interstadial (approximately 14,700 to 12,900 years ago)—a time that others have suggested might have led to local woolly mammoth extinctions. However, the genomes of mammoths studied through this time period don’t indicate that the warming had any adverse effects.

Adverse effects only appeared—and drastically so—once the population was isolated on that island.

The team’s simulations indicate that, at its smallest, the total population of Wrangel Island mammoths was fewer than 10 individuals. This represents a severe population bottleneck. This was seen genetically through increased runs of homozygosity within the genome, caused when both parents contribute nearly identical chromosomes, both derived from a recent ancestor. The runs of homozygosity within isolated Wrangel Island mammoths were four times as great as those before sea levels rose.

Despite that dangerously tiny number of mammoths, they recovered. The population size, as well as inbreeding level and genetic diversity, remained stable for the next 6,000 years until their extinction. Unlike the initial population bottleneck, genomic signatures over time seem to indicate inbreeding eventually shifted to pairings of more distant relatives, suggesting either a larger mammoth population or a change in behavior.

Within 20 generations, their simulations indicate, the population size would have increased to about 200–300 mammoths. This is consistent with the slower decrease in heterozygosity that they found in the genome.

Long-lasting negative effects

The Wrangel Island mammoths may have survived despite the odds, and harmful genetic defects may not have been the reason for their extinction, but the research suggests their story is complicated.

At about 7,608 square kilometers today, a bit larger than the island of Crete, Wrangel Island would have offered a fair amount of space and resources, although these were large animals. For 6,000 years following their isolation, for example, they suffered from inbreeding depression, which refers to increased mortality as a result of inbreeding and its resulting defects.

That inbreeding also boosted the purging of harmful mutations. That may sound like a good thing—and it can be—but it typically occurs because individuals carrying two copies of harmful mutations die or fail to reproduce. So it’s good only if the population survives it.

The team’s results show that purging genetic mutations can be a lengthy evolutionary process. Lead author Marianne Dehasque is a paleogeneticist who completed her PhD at the Centre for Palaeogenetics. She explained to Ars that, “Purging harmful mutations for over 6,000 years basically indicates long-lasting negative effects caused by these extremely harmful mutations. Since purging in the Wrangel Island population went on for such a long time, it indicates that the population was experiencing negative effects from these mutations up until its extinction.”
