Sorry for the delay in response.
Here I look at it from a purely memetic perspective - you can imagine thinking as a self-interested memplex. Note I'm not claiming this is the main useful perspective, or this should be the main perspective to take.
Basically, from this perspective
* the more people think about AI race, the easier is to imagine AI doom. Also the specific artifacts produced by AI race make people more worried - ChatGPT and GPT-4 likely did more for normalizing and spreading worried about AI doom than all the previous AI safety outreach together.
The more the AI race is clear reality people agree on, the more attentional power and brainpower you will get.
* but also from the opposite direction... : one of the central claim of the doom memplex is AI systems will be incredibly powerful in our lifetimes - powerful enough to commit omnicide, take over the world, etc. - and their construction is highly convergent. If you buy into this, and you are certain type of person, you are pulled toward "being in this game". Subjectively, it's much better if you - the risk-aware, pro-humanity player - are at the front. Safety concerns of Elon Musk leading to founding of OpenAI likely did more to advance AGI than all advocacy of Kurzweil-type accelerationist until that point...
Empirically, the more people buy into the "single powerful AI systems are incredibly dangerous", the more attention goes toward work on such system.
Both memeplexes share a decent amount of maps, which tend to work as blueprints or self-fullfilling prophecies for what to aim for.
Personally, I think the 1:1 meme is deeply confused.
A helpful analogy (thanks to Ollie Base) is with nutrition. Imagine someone hearing that "chia seeds are the nutritionally most valuable food, top rated in surveys" ... and subsequently deciding to eat just chia seeds, and nothing else!
In my view, sort of obviously, intellectual conference diet consisting just of 1:1s is poor and unhealthy for almost everyone.
In my view this is a bad decision.
As I wrote on LW
Sorry but my rough impression from the post is you seem to be at least as confused about where the difficulties are as average of alignment researchers you think are not on the ball - and the style of somewhat strawmanning everyone & strong words is a bit irritating.
In particular I don't appreciate the epistemic of these moves together
1. Appeal to seeing thinks from close proximity. Then I got to see things more up close. And here’s the thing: nobody’s actually on the friggin’ ball on this one!
2. Straw-manning and weakmaning what almost everyone else thinks and is doing
3. Use of an emotionally compelling words like 'real science' for vaguely defined subjects where the content may be the opposite of what people imagine. Is the empirical alchemy-style ML type of research what's advocated for as the real science?
4. What overall sounds more like the aim is to persuade, rather than explain
I think curating this signals this type of bad epistemics is fine, as long as you are strawmanning and misrepresenting others in a legible way and your writing is persuasive. Also there is no need to actually engage with existing arguments, you can just claim seeing things more up close.
Also to what extent are moderator decisions influenced by status and centrality in the community...
... if someone new and non-central to the community came up with this brilliant set of ideas how to solve AI safety:
1. everyone working on it is not on the ball. why? they are all working on wrong things!
2. promising is to do something very close to how empirical ML capabilities research works
3. this is a type of problem where you can just throw money at it and attract better ML talent
... I doubt this would have a high chance of becoming curated.
Copy-pasting here from LW.
Sorry but my rough impression from the post is you seem to be at least as confused about where the difficulties are as average of alignment researchers you think are not on the ball - and the style of somewhat strawmanning everyone & strong words is a bit irritating.
Maybe I'm getting it wrong, but it seems the model you have for why everyone is not on the ball is something like "people are approaching it too much from a theory perspective, and promising approach is very close to how empirical ML capabilities research works" & "this is a type of problem where you can just throw money at it and attract better ML talent".
I don't think these two insights are promising.
Also, again, maybe I'm getting it wrong, but I'm confused how similar you are imagining the current systems to be to the dangerous systems. It seems either the superhuman-level problems (eg not lying in a way no human can recognize) are somewhat continuous with current problems (eg not lying), and in that case it is possible to study them empirically. Or they are not. But different parts of the post seem to point in different directions. (Personally I think the problem is somewhat continuous, but many of the human-in-the-loop solutions are not, and just break down.)
Also, with what you find promising I'm confused what do you think the 'real science' to aim for is - on one hand it seems you think the closer the thing is to how ML is done in practice the more real science it is. On the other hand, in your view all deep learning progress has been empirical, often via dumb hacks and intuitions (this isn't true imo).

While the claim - the task ‘predict next token on the internet’ absolutely does not imply learning it caps at human-level intelligence - is true, some parts of the post and reasoning leading to the claims at the end of the post are confused or wrong.
Let’s start from the end and try to figure out what goes wrong.
From a high-level perspective, it is clear that this is just wrong. Part of what human brains are doing is to minimise prediction error with regard to sensory inputs. Unbounded version of the task is basically of same generality and difficulty as what GPT is doing, and is roughly equivalent to understand everything what is understandable in the observable universe. For example: a friend of mine worked at analysing the data from LHC, leading to the Higgs detection paper. Doing this type of work basically requires a human brain to have a predictive model of aggregates of outputs of a very large number of collisions of high-energy particles, processed by a complex configuration of computers and detectors.
Where GPT and humans differ is not some general mathematical fact about the task, but differences in what sensory data is a human and GPT trying to predict, and differences in cognitive architecture and ways how the systems are bounded. The different landscape of both boundedness and architecture can lead to both convergent cognition (thinking as the human would do) and the opposite, predicting what the human would output in highly non-human way.
The boundedness is overall a central concept here. Neither humans nor GPTs are attempting to solve ‘how to predict stuff with unlimited resources’, but a problem of cognitive economy - how to allocate limited computational resources to minimise prediction error.
If I try to imagine a mind which is able to predict my next word when asked to make up random words, and be successful at assigning 20% probability to my true output, I’m firmly in the realm of weird and incomprehensible Gods. If the Mind is imaginably bounded and smart, it seems likely it would not devote much cognitive capacity to trying to model in detail strings prefaced by a context like ‘this is a list of random numbers’, in particular if inverting the process generating the numbers would seem really costly. Being this good at this task would require so much data and cheap computation that this is way beyond superintelligence, in the realm of philosophical experiments.
Overall I think it is really unfortunate way how to think about the problem, where a system which is moderately hard to comprehend (like GPT) is replaced by something much more incomprehensible. Also it seems a bit of a reverse intuition pump - I’m pretty confident most people's intuitive thinking about this ’simplest’ thing will be utterly confused.
How did we got here?
Apart from the fact that humans are also able to rap battle or impro on the fly, notice that “what would the loss function like the system to do” in principle tells you very little about what the system will do. For example, the human loss function makes some people attempt to predict winning lottery numbers. This is an impossible task for humans and you can’t say much about the human based on this. Or you can speculate about minds which would be able to succeed in this task, but you soon get into the realm of Gods and outside of physics.
Again, from the cognitive economy perspective, predicting my errors would often be wasteful. With some simplification, you can imagine I make two types of errors - systematic, and random. Often the simplest way how to predict the systematic error would be to emulate the process which led to the error. Random errors are ... random, and a mind which knows me in enough detail to predict which random errors I’ll make seems a bit like the mind predicting the lottery numbers.
The general claim that some predictions are really hard and you need superhuman powers to be good at them is true, but notice that this does not inform us about what GPT-x will learn.
Yes this is clearly true: in the limit the task is of unlimited difficulty.
You are correct with some of the criticism, but as a side-note, completeness is actually crazy.
All real agents are bounded, and pay non-zero costs for bits, and as a consequence, don't have complete preferences. Complete agents in real world do not exist. If they existed, correct intuitive model of them wouldn't be 'rational players' but 'utterly scary god, much bigger than the universe they live in'.
Sequoia led FTX round B in Jul 2021 and had notably more time to notice any irregularities than grant recipients.
b.
I would expect the funds to have much better expertise in something like "evaluating the financial health of a company".
Also it seem you are somewhat shifting the goalposts: Zoe's paragraph with "On Halloween this past year, I was hanging out with a few EAs." It is reasonable to assume the reader will interpret it as hanging out with basically random/typical EAs, and the argument should hold for these people. Your argument would work better if she was hanging out with "EAs working at FTX" or "EAs advising SBF" who could have probably done better than funds on evaluating stuff like how the specific people work.
In my view this is an example of a mistake in bounded/local consequentialism
From deontic perspective, there is a coordination problem, where "at least consistent handle" posts can be somewhat costly for the poster, but an atmosphere of an earnest discussion of real people has large social benefits. Vice versa, discussion with a large fraction of anonymous accounts - in particular if they are sniping at real people and each other - decreases trust, and is vulnerable to manipulation by sock puppets and nefarious players.
Also, I think there are some virtue ethics costs associated with anonymous posts, roughly in the direction of transparency and integrity.
For example, if I imagine myself anonymously posting something critical received unfavourably by someone, and later, meeting that someone in person, or collaborating on something relevant, I would find it integrity-decreasing to continue hiding the authorship. And if I'd be happy to reveal my identity to the people upset ... why not reveal it directly?
While I don't think these considerations add up to "never post anonymously", I think they are pretty large, and usually much larger than e.g. "small probability of adverse career effects in the EA ecosystem".
Seems worth trying
At the same time, I don't think the community post / frontpage attention mechanism is the core of what's going on. Which is, in my guess, often best understood as a fight between memeplexes about hearts and minds
The quality of reasoning in the text seems somewhat troublesome. Using two paragraphs as example
It appears that a chunk of Zoe's epistemic risk bears a striking resemblance to financial risk. For instance, if one simply knew more about tomorrow's stock prices, they could sidestep all stock market losses and potentially become stupendously rich.
This highlights the fact that gaining knowledge in certain domains can be difficult task, with big hedge funds splashing billions and hiring some of the brightest minds just to gain a slight edge in simply knowing a bit more about asset prices. It extends to having more info about which companies may go belly up or engage in fraud.
Acquiring more knowledge comes at a cost. Processing knowledge comes at cost. Choosing ignorance is mostly not a result of recklessness or EA institutional design but a practical choice given the resources required to process information. It's actually rational for everyone to ignore most information most of the time (this is standard econ, check rational inattention and extensive literature on the topic).
One real question in this space is if EAs have allocated their attention wisely. The answer seems to be "mostly yes." In case of FTX, heavyweights like Temasek, Sequoia Capital, and SoftBank with billions on the line did their due diligence but still missed what was happening. Expecting EAs to be better evaluators of FTX's health than established hedge funds is somewhat odd. EAs, like everyone else, face the challenge of allocating attention and their expertise lies in "using money for good" rather than "evaluating the health of big financial institutions". For the typical FTX grant recipient to assume they need to be smarter than Sequoia or SoftBank about FTX would likely not be a sound decision.
