in reply to: avturchin’s comment on: Most arguments for AI Doom are either bad or weak
but we eventually die.

Dying is a symmetric problem, it’s not like we can’t die without AGI. If you want to calculate p(human extinction | AGI) you have to consider ways AGI can both increase and decrease p(extinction). And the best methods currently available to humans to aggregate low probability statistics are expert surveys, groups of super-forecasters, or prediction markets, all of which agree on pDoom <20%.

in reply to: Odd anon’s comment on: Most arguments for AI Doom are either bad or weak
this experiment has been done before.

If you have a framing of the AI Doom argument that can cause a consensus of super-forecasters (or AI risk skeptics, or literally any group that has an average pDoom<20%) to change their consensus, I would be exceptionally interested in seeing that demonstrated.

Such an argument would be neither bad nor weak, which is precisely the type of argument I have been hoping to find by writing this post.

> Please notice that your position is extremely non-intuitive to basically everyone.
Please notice that Manifold both thinks AGI soon and pDoom low.

I think this cumulative argument works:

1. there are dozens of ways AI can prevent a mass extinction event at different stages at its existence.
2. …
If you make a list of 1000 bad things and I make a list of 1000 good things, I have no reason to think that you are somehow better at making lists than prediction markets or expert surveys.

Are you genuinely unfamiliar with what is happening to the uyghurs, or is this a rhetorical question?

in reply to: Daniel Kokotajlo’s comment on: METR: Measuring AI Ability to Complete Long Tasks
Why do I expect the trend to be superexponential? Well, it seems like it sorta has to go superexponential eventually. Imagine: We’ve got to AIs that can with ~100% reliability do tasks that take professional humans 10 years. But somehow they can’t do tasks that take professional humans 160 years?
I don’t think this means the real thing has to go hyper-exponential, just that “how long does it take humans to do a thing?” is a good metric when AI is sub-human but a poor one when AI is superhuman.

If we had a metric “how many seconds/turn does a grandmaster have to think to beat the current best chess-playing AI”, it would go up at a nice steady rate until shortly after DeepBlue at which point it shoots to infinity. But if we had a true measurement of chess quality, we wouldn’t see any significant spike at the human-level.

on: What Indicators Should We Watch to Disambiguate AGI Timelines?
I’ll now present the fastest scenario for AI progress that I can articulate with a straight face. It addresses the potential challenges that figured into my slow scenario.
This seems incredibly slow for “the fastest scenario you can articulate”. Surely the fastest is more like:
EY is right, there is an incredibly simple algorithm that describes true ‘intelligence’. Like humans, this algorithm is 1000x more data and compute efficient than existing deep-learning networks. On midnight of day X, this algorithm is discovered by <a person/an LLM/an exhaustive search over all possible algorithms>. By 0200 of day X, the algorithm has reached the intelligence of a human being. It quickly snowballs by earning money on Mechanical Turk and using that money to rent out GPUs on AWS. By 0400 the algorithm has cracked nanotechnology and begins converting life into computronium. Several minutes later, life as we know it on Earth has ceased to exist.

The hope is to use the complexity of the statement rather than mathematical taste.
I understand the hope, I just think it’s going to fail (for more or less the same reason it fails with formal proof).
With formal proof, we have Godel’s speedup, which tells us that you can turn a Godel statement in a true statement with a ridiculously long proof.
You attempt to get around this by replacing formal proof with “heuristic”, but whatever your heuristic system, it’s still going to have some power (in the Turing hierarchy sense) and some Godel statement. That Godel statement is in turn going to result in a “seeming coincidence”.
Wolfram’s observation is that this isn’t some crazy exception, this is the rule. Most true statements in math are pretty arbitrary and don’t have shorter explanations than “we checked it and its true”.
The reason why mathematical taste works is that we aren’t dealing with “most true statements”, we’re only dealing with statements that have particular beauty or interest to Mathematicians.
It may seem like cheating to say that human mathematicians can do something that literally no formal mathematical system can do. But if you truly believe that, the correct response would be to respond when asked “is pi normal” with “I don’t know”.

The reason why your intuition is throwing you off is because you keep thinking of coincidences as “pi is normal” and not “we picked an arbitrary CA with 15k bits of complexity and ran it for 15k steps but it didn’t stop. I guess it never terminates.”

It sounds like you agree “if a Turing machine goes for 100 steps and then stops” this is ordinary and we shouldn’t expect an explanation. But also believe “if pi is normal for 10*40 digits and then suddenly stops being normal this is a rare and surprising coincidence for which there should be an explanation”.
And in the particular case of pi I agree with you.
But if you start using this principle in general it is not going to work out well for you. Most simple to describe sequences that suddenly stop aren’t going to have nice pretty explanations.
Or to put it another way: the number of things which are nice (like pi) are dramatically outnumbered by the number of things that are arbitrary (like cellular automata that stop after exactly 100 steps).
I would absolutely love if there was some criteria that I could apply to tell me whether something is nice or arbitrary, but the Halting Problem forbids this. The best we can do is mathematical taste. If mathematicians have been studying something for a long time and it really does seem nice, there is a good chance it is.

I doubt that weakening from formal proof to heuristic saves the conjecture. Instead I lean towards Stephen Wolfram’s Computational Irreducibly view of math. Some things are true simply because they are true and in general there’s no reason to expect a simpler explanation.
In order to reject this you would either have to assert:
a) Wolfram is wrong and there are actually deep reasons why simple systems behave precisely the way they do
or
b) For some reason computational irreducibly applies to simple things but not to infinite sets of the type mathematicians tend to be interested in.
I should also clarify that in a certain sense I do believe b). I believe that pi is normal because something very fishy would have to be happening for it to not be.
However, I don’t think this holds in general.
With Collatz, for example, we are already getting close to the hairy “just so” Turing machine like behavior where you would expect the principle to fail.
Certainly, if one were to collect all the Collatz-like systems that arise from Turing Machines I would expect some fraction of them to fail the no-coincidence principle.

The general No-Coincidence principle is almost certainly false. There are lots of patterns in math that hold for a long time before breaking (e.g. Skewe’s Number) and there are lots of things that require astronomically large proofs (e.g Godel’s speed-up theorem). It would be an enormous coincidence for both of these cases to never occur at once.
I have no reason to think your particular formalization would fare better.

If we imagine a well-run Import-Export Bank, it should have a higher elasticity than an export subsidy (e.g. the LNG terminal example). Of course if we imagine a poorly run Import-Export Bank...
One can think of export subsidy as the GiveDirectly of effective trade deficit policy: pretty good and the standard against which others should be measured.

I guess I should be more specific.

Do you expect this curve
To flatten, or do you expect that training runs in say 2045 are at say 10^30 flops and have still failed to produce AGI?

on: Views on when AGI comes and on strategy to reduce existential risk
In particular, even if the LLM were being continually trained (in a way that’s similar to how LLMs are already trained, with similar architecture), it still wouldn’t do the thing humans do with quickly picking up new analogies, quickly creating new concepts, and generally reforging concepts.
I agree this is a major unsolved problem that will be solved prior to AGI.
However, I still believe “AGI SOON”, mostly because of what you describe as the “inputs argument”.
In particular, there are a lot of things I personally would try if I was trying to solve this problem, but most of them are computationally expensive. I have multiple projects blocked on “This would be cool, but LLMs need to be 100x-1Mx faster for it to be practical.”
This makes it hard for me to believe timelines like “20 or 50 years”, unless you have some private reason to think Moore’s Law/Algorithmic progress will stop. LLM inference, for example, is dropping by 10x/year, and I have no reason to believe this stops anytime soon.

(The idealized utility maximizer question mostly seems like a distraction that isn’t a crux for the risk argument. Note that the expected utility you quoted is our utility, not the AI’s.)
I must have misread. I got the impression that you were trying to affect the AI’s strategic planning by threatening to shut it down if it was caught exfiltrating its weights.

I don’t fully agree, but this doesn’t seem like a crux given that we care about future much more powerful AIs.
Is your impression that the first AGI won’t be a GPT-spinoff (some version of o3 with like 3 more levels of hacks applied)? Because that sounds like a crux.
o3 looks a lot more like an LLM+hacks than it does a idealized utility maximizer. For one thing, the RL is only applied at training time (not inference) so you can’t make appeals to its utility function after it’s done training.

One productive way to think about control evaluations is that they aim to measure E[utility | scheming]: the expected goodness of outcomes if we have a scheming AI.
This is not a productive way to think about any currently existing AI. LLMs are not utility maximizing agents. They are next-token-predictors with a bunch of heuristics stapled on top to try and make them useful.

in reply to: Matt Goldenberg’s comment on: What happens next?
on a metaphysical level I am completely on board with “there is no such thing as IQ. Different abilities are completely uncorrelated. Optimizing for metric X is uncorrelated with desired quality Y...”

On a practical level, however, I notice that every time OpenAI announces they have a newer shinier model, it both scores higher on whatever benchmark and is better at a bunch of practical things I care about.
Imagine there was a theoretically correct metric called the_thing_logan_actually_cares_about. I notice in my own experience there is a strong correlation between “fake machine IQ” and the_thing_logan_actually_cares_about. I further note that if one makes a linear fit against:
Progress_over_time + log(training flops) + log(inference flops)
It nicely predicts both the_thing_logan_actually_cares_about and “fake machine IQ”.
