Hi I'm Steve Byrnes, an AGI safety / AI alignment researcher in Boston, MA, USA, with a particular focus on brain algorithms. See https://sjbyrnes.com/agi.html for a summary of my research and sorted list of writing. Physicist by training. Email: steven.byrnes@gmail.com. Leave me anonymous feedback here. I’m also at: RSS feed , Twitter , Mastodon , Threads , Bluesky , GitHub , Wikipedia , Physics-StackExchange , LinkedIn
I agree with Chollet (and OP) that LLMs will probably plateau, but I’m also big into AGI safety—see e.g. my post AI doom from an LLM-plateau-ist perspective.
(When I say “AGI” I think I’m talking about the same thing that you called digital “beings” in this comment.)
Here are a bunch of agreements & disagreements.
if François is right, then I think this should be considered strong evidence that work on AI Safety is not overwhelmingly valuable, and may not be one of the most promising ways to have a positive impact on the world.
I think François is right, but I do think that work on AI safety is overwhelmingly valuable.
Here’s an allegory:
There’s a fast-breeding species of extraordinarily competent and ambitious intelligent aliens. They can do science much much better than Einstein, they can run businesses much much better than Bezos, they can win allies and influence much much better than Hitler or Stalin, etc. And they’re almost definitely (say >>90% chance) coming to Earth sooner or later, in massive numbers that will keep inexorably growing, but we don’t know exactly when this will happen, and we also don’t know in great detail what these aliens will be like—maybe they will have callous disregard for human welfare, or maybe they’ll be great. People have been sounding the alarm for decades that this is a big friggin’ deal that warrants great care and advanced planning, but basically nobody cares.
Then some scientist Dr. S says “hey those dots in the sky—maybe they’re the aliens! If so they might arrive in the next 5-10 years, and they’ll have the following specific properties”. All of the sudden there’s a massive influx of societal interest—interest in the dots in particular, and interest in alien preparation in general.
But it turns out that Dr. S was wrong! The dots are small meteors. They might hit earth and cause minor damage but nothing unprecedented. So we’re back to not knowing when the aliens will come or what exactly they’ll be like.
Is Dr. S’s mistake “strong evidence that alien prep is not overwhelmingly valuable”? No! It just puts us back where we were before Dr. S came along.
(end of allegory)
(Glossary: the “aliens” are AGIs; the dots in the sky are LLMs; and Dr. S would be a guy saying LLMs will scale to AGI with no additional algorithmic insights.)
It would make AI Safety work less tractable
If LLMs will plateau (as I expect), I think there are nevertheless lots of tractable projects that would help AGI safety. Examples include:
It seems that many people in Open Phil have substantially shortened their timelines recently (see Ajeya here).
For what it’s worth, Yann LeCun is very confidently against LLMs scaling to AGI, and yet LeCun seems to have at least vaguely similar timelines-to-AGI as Ajeya does in that link.
Ditto for me.
See also my discussion here (“30 years is a long time. A lot can happen. Thirty years ago, deep learning was an obscure backwater within AI, and meanwhile people would brag about how their fancy new home computer had a whopping 8 MB of RAM…”)
To be clear, you can definitely find some people in AI safety saying AGI is likely in <5 years, although Ajeya is not one of those people. This is a more extreme claim, and does seem pretty implausible unless LLMs will scale to AGI.
I think this makes me very concern of a strong ideological and philosophical bubble in the Bay regarding these core questions of AI.
Yeah some examples would be:
Many ≠ All! But to the extent that these things happen, I’m against it, and I do complain about it regularly.
(To be clear, I’m not opposed to contingency-planning for the possibility that LLMs will scale to AGIs. I don’t expect that contingency to happen, but hey, what do I know, I’ve been wrong before, and so has Chollet. But I find that these kinds of claims above are often stated unconditionally. Or even if they’re stated conditionally, the conditionality is kinda forgotten in practice.)
I think it’s also important to note that these habits above are regrettably common among both AI pessimists and AI optimists. As examples of the latter, see me replying to Matt Barnett and me replying to Quintin Pope & Nora Belrose.
By the way, this might be overly-cynical, but I think there are some people (coming into the AI safety field very recently) who understand how LLMs work but don’t know how (for example) model-based reinforcement learning works, and so they just assume that the way LLMs work is the only possible way for any AI algorithm to work.
On the whole though, I think much of the case by proponents for the importance of working on AI Safety does assume that current paradigm + scale is all you need, or rest on works that assume it.
Yeah this is more true than I would like. I try to push back on it where possible, e.g. my post AI doom from an LLM-plateau-ist perspective.
There were however plenty of people who were loudly arguing that it was important to work on AI x-risk before “the current paradigm” was much of a thing (or in some cases long before “the current paradigm” existed at all), and I think their arguments were sound at the time and remain sound today. (E.g. Alan Turing, Norbert Weiner, Yudkowsky, Bostrom, Stuart Russell, Tegmark…) (OpenPhil seems to have started working seriously on AI in 2016, which was 3 years before GPT-2.)
I’m confused what you’re trying to say… Supposing we do in fact invent AGI someday, do you think this AGI won’t be able to do science? Or that it will be able to do science, but that wouldn’t count as “automating science”?
Or maybe when you said “whether 'PASTA' is possible at all”, you meant “whether 'PASTA' is possible at all via future LLMs”?
Maybe you’re assuming that everyone here has a shared assumption that we’re just talking about LLMs, and that if someone says “AI will never do X” they obviously means “LLMs will never do X”? If so, I think that’s wrong (or at least I hope it’s wrong), and I think we should be more careful with our terminology. AI is broader than LLMs. …Well maybe Aschenbrenner is thinking that way, but I bet that if you were to ask a typical senior person in AI x-risk (e.g. Karnofsky) whether it’s possible that there will be some big AI paradigm shift (away from LLMs) between now and TAI, they would say “Well yeah duh of course that’s possible,” and then they would say that they would still absolutely want to talk about and prepare for TAI, in whatever algorithmic form it might take.
OK yeah, “AGI is possible on chips but only if you have 1e100 of them or whatever” is certainly a conceivable possibility. :) For example, here’s me responding to someone arguing along those lines.
If there are any neuroscientists who have investigated this I would be interested!
There is never a neuroscience consensus but fwiw I fancy myself a neuroscientist and have some thoughts at: Thoughts on hardware / compute requirements for AGI.
One of various points I bring up is that:
My view is: implementing (1) via (3) would involve a lot of inefficient bottlenecks where there’s no low-level affordance that’s a good match to the algorithmic operation we want … but the same is true of implementing (1) via (2). Indeed, I think the human brain does what it does via some atrociously inefficient workarounds to the limitations of biological neurons, limitations which would not be applicable to silicon chips.
By contrast, many people thinking about this problem are often thinking about “how hard is it to use (3) to precisely emulate (2)?”, rather than “what’s the comparison between (1)←(3) versus (1)←(2)?”. (If you’re still not following, see my discussion here—search for “transistor-by-transistor simulation of a pocket calculator microcontroller chip”.)
Another thing is that, if you look at what a single consumer GPU can do when it runs an LLM or diffusion model… well it’s not doing human-level AGI, but it’s sure doing something, and I think it’s a sound intuition (albeit hard to formalize) to say “well it kinda seems implausible that the brain is doing something that’s >1000× harder to calculate than that”.
Yeah sure, here are two reasonable positions:
I think plenty of AI safety people are in (A), which is at least internally-consistent even if I happen to think they’re wrong. I also think there are also lots of AI safety people who would say that they’re in (B) if pressed, but where they long ago lost track of the fact that that’s what they were doing and instead they’ve started treating the contingency as a definite expectation, and thus they say things that omit essential caveats, or are wrong or misleading in other ways. ¯\_(ツ)_/¯
A big crux I think here is whether 'PASTA' is possible at all, or at least whether it can be used as a way to bootstrap everything else.
Do you mean “possible at all using LLM technology” or do you mean “possible at all using any possible AI algorithm that will ever be invented”?
As for the latter, I think (or at least, I hope!) that there’s wide consensus that whatever human brains do (individually and collectively), it is possible in principle for algorithms-running-on-chips to do those same things too. Brains are not magic, right?
I was under the impression that most people in AI safety felt this way—that transformers (or diffusion models) weren't going to be the major underpinning of AGI.
I haven’t done any surveys or anything, but that seems very inaccurate to me. I would have guessed that >90% of “people in AI safety” are either strongly expecting that transformers (or diffusion models) will be the major underpinning of AGI, or at least they’re acting as if they strongly expect that. (I’m including LLMs + scaffolding and so on in this category.)
For example: people seem very happy to make guesses about what tasks the first AGIs will be better and worse at doing based on current LLM capabilities; and people seem very happy to make guesses about how much compute the first AGIs will require based on current LLM compute requirements; and people seem very happy to make guesses about which companies are likely to develop AGIs based on which companies are best at training LLMs today; and people seem very happy to make guesses about AGI UIs based on the particular LLM interface of “context window → output token”; etc. etc. This kind of thing happens constantly, and sometimes I feel like I’m the only one who even notices. It drives me nuts.
Hi, I’m an AI alignment technical researcher who mostly works independently, and I’m in the market for a new productivity coach / accountability buddy, to chat with periodically (I’ve been doing one ≈20-minute meeting every 2 weeks) about work habits, and set goals, and so on. I’m open to either paying fair market rate, or to a reciprocal arrangement where we trade advice and promises etc. I slightly prefer someone not directly involved in AI alignment—since I don’t want us to get nerd-sniped into object-level discussions—but whatever, that’s not a hard requirement. You can reply here, or DM or email me. :) update: I’m all set now
Humans are less than maximally aligned with each other (e.g. we care less about the welfare of a random stranger than about our own welfare), and humans are also less than maximally misaligned with each other (e.g. most people don’t feel a sadistic desire for random strangers to suffer). I hope that everyone can agree about both those obvious things.
That still leaves the question of where we are on the vast spectrum in between those two extremes. But I think your claim “humans are largely misaligned with each other” is not meaningful enough to argue about. What percentage is “largely”, and how do we even measure that?
Anyway, I am concerned that future AIs will be more misaligned with random humans than random humans are with each other, and that this difference will have important bad consequences, and I also think there are other disanalogies / reasons-for-concern as well. But this is supposed to be a post about terminology so maybe we shouldn’t get into that kind of stuff here.
Oh hey here’s one more: Chollet himself (!!!) has vaguely similar timelines-to-AGI (source) as Ajeya does. (Actually if anything Chollet expects it a bit sooner: he says 2038-2048, Ajeya says median 2050.)
