Love it, but sad that the FTX song didn’t make it.
Between the cosmic endowment, the doomsday argument, and simulation theory, my sense of cosmic importance has been yoyoing across ~60 orders of magnitude.
It’s crazy how realistic sci-fi sounds these days.
And newer approaches[8] seem to eliminate the problem entirely, so it is now a contingent engineering limitation rather than a fundamental critique of LLMs.
Only skimmed it, but I think the two main contributions are a way to generate useful synthetic text from a limited corpus so pretraining can keep improving even when new real data is scarce (paper), and an automated AI research loop design (paper), a bit more fancy and automated, but similar to what Karpathy has recently been posting about.
If you’re looking for examples of LLMs that do weight based continual learning/belief update, the Titans, and Nested Learning papers might be a better fit (I described them in a recent post), or, if you want something closer to a vanilla transformer architecture, E2E-TTT.
I recently wrote a post surveying some weight based continual learning research that you may find interesting.
I agree that because base models can have such broad pre-existing knowledge and skills, can be trained with RL to manage context and memories externally, and have a super-human context window/working memory, weight-based continual learning isn’t strictly necessary to get to some fairly powerful systems, probably able to automate much of white-collar work. But I also suspect that weight-based continual learning may not be that far off, and that it could offer some qualitative advantages leading to faster capability progress than we otherwise would have.
Are We in a Continual Learning Overhang?
WebGPT probably already can, because it can use a text based browser and look up the answer. https://openai.com/blog/webgpt/
Worth noting though that you should expect those who are most successful at getting more of what they want to have a utility function with a big overlap with the utility function of others, and to be able to credibly commit to not destroy value for other people. We live in a society.

There’s a lot of value to be had in understanding the wisdom of existing informal evaluation systems and scaling them into formal ones.
One consideration to keep in mind though is that there might also be a social function in the informality and vagueness of many evaluation systems.
From Social Capital in Silicon Valley:
The illegibility and opacity of intra-group status was doing something really important – it created space where everyone could belong. The light of day poisons the magic. It’s a delightful paradox: a group that exists to confer social status will fall apart the minute that relative status within the group is made explicit. There’s real social value in the ambiguity: the more there is, the more people can plausibly join, before it fractures into subgroups.
There is probably a lot to be improved with current evaluation systems, but one always has to be careful with those fences.
I maybe wasn’t clear about what I meant by ‘the game.’ I didn’t mean how to be a good public intellectual but rather the broader ‘game’ of coming up with new ideas and figuring things out.
One important metric I use to judge public intellectuals is whether they share my views, and start from similar assumptions. It’s obviously important to not filter too strongly on this or you’re never going to hear anything that challenges your beliefs, but it still makes sense to discount the views of people who hold beliefs you think are false. But you obviously can’t build an objective metric based on how much someone agrees with you.
The issue is that one of the most important metrics I use to quickly measure the merits of an intellectual is inherently subjective. You can’t have your system based on adjudicating the truth of disputed claims.
I like the thought. Though unlike sports, intellectual work seems fundamentally open-ended, and therefore doesn’t seem to allow for easy metrics. Intellectuals aren’t the ones playing the game, they’re the ones figuring out the rules of the game. I think that’s why it often is better to focus on the ideas rather than the people.
A similar question also applies within academia. There, citation counts already serve as a metric to measure intellectual accomplishment. The goodharting of that metric probably can tell you a lot about the challenges such a system would face. What metrics do you have in mind?
In a way, this problem is just scaling up the old reputation/prestige system. You find people you respect and trust, and then you see who they respect and trust, and so on. While regularly checking for local validity of course. Maybe some kind of social app inspired by liquid democracy/quadratic voting might work? You enter how much you trust and respect a few public intellectuals (who themselves entered how much they trust other intellectuals) and then it computes how much you can trust everyone else.
True. I still think that market solutions would arise. Income Sharing Agreements (ISA) in particular seem promising for this kind of situation.
I agree that it is less bad in Europe and the UK. To quote from a response I gave to a related question:
“I see the education in countries where it is free/mostly free as better than the US, but many of the same criticisms still apply. What is taught, and how it is taught is the same as in the Anglo-saxon World. See here.
Also, the higher education system in those other countries is still quite wasteful (people learning things they don’t need or want to learn, zero-sum competition for credentials...). It’s just that the cost is borne by the taxpayer and not the students themselves. This is probably better than getting young people deep into debt, but still not great.
I think that countries where higher education is free are more ‘locked-in’. So, I’m much more hopeful about significant improvements coming out of the Anglo-saxon world than out of continental Europe, since in Europe any innovative education startup has to compete with a free alternative.”
On the question of AI safety work being done in academia, it is my understanding that many people working in academia have to hide the true intent of their research, or frame it in some way that sounds more in line with more traditional lines of inquiry. This post has some interesting discussions on this topic: Intellectual Progress Inside and Outside Academia.
There’s an old question, “What does the Bible God need to do for the Christians to say he is not good?” What would academia need to do before you let it go? -Yudkowsky
By “if public education is all about helping employers in their hiring process” I am only referring to the ~80% signaling. I mean to say that the government shouldn’t help companies select candidates, and definitely not in such a wasteful manner.
I agree that increasing human capital is a good goal (alongside creating the public good of an educated citizenry). It’s just that the government does this very very inefficiently. I discuss this in more details in The Case for Education
If public education is all about helping employers in their hiring process, then it’s a really wasteful form of corporate welfare. So, I don’t really consider this as a good argument in favor of funding public higher education.
I think that fixing the education system will require unbundling the learning part and the signaling part. So, learning communities for the learning part, and comprehensive standardized exams for the signaling. Not sure how elaborate the exams need to be to match the signal quality of a college degree. I guess for people mostly looking to signal intelligence, conscientiousness or specific abilities or knowledge, the exams can be quite short and inexpensive as long as they’re challenging enough (something like the final exams of graduate level classes).
I do agree that it has a purpose. I discuss two of those: increasing human capital and the public good of an educated citizenry. Do you have any others in mind?
My goal isn’t necessarily to directly improve education for the median knowledge-worker. I want to start by improving it for smarter and more self-directed students and then see for how well it can generalize. Focusing on smart people first is kinda the point, since if the system you build attracts smart people, it’s going to be a stronger signal of intelligence.
But I think you underestimate how many people would see my proposed model as an improvement. Just taking the field of programming, the project I’d like to start would make it easier for all those who already get into programming without a formal education, and all those who’d like to, but lack the social support and accountability to be successful following that route. I think that represents a decent amount of people.
And it’s not as if the population of intrinsically curious people is restricted to people who are math-inclined.
I wouldn’t be surprised if the kind of environment I envision, with someone responsible to keep people on track and hold people accountable, would in fact be better for most students than the Zoom university they are getting now.
Not sure what risks you are thinking of. My own project at least just seems like a competitor to bootcamps, except >3x cheaper. I don’t think anything I’m proposing is particularly risky. Could you elaborate on this?
The EA Hotel specifically, I’m not quite sure. As I said, most people would need more accountability. But I’m fairly confident that the kind of environment I envision, with someone responsible to keep people on track and hold people accountable, would be better for most students than the Zoom university they are getting now.
Nice, thanks!
