It's an interesting premise, but how many people

- are capable of evaluating the LLM's output to the degree that they can identify truly unique insights

- are prompting the LLM in such a way that it could produce truly unique insights

I've prompted an LLM upwards of 1,000 times in the last month, but I doubt more than 10 of my prompts were sophisticated enough to even allow for a unique insight. (I spend a lot of time prompting it to improve React code.) And of those 10 prompts, even if all of the outputs were unique, I don't think I could have identified a single one.

I very much do like the idea of the day-dreaming loop, though! I actually feel like I've had the exact same idea at some point (ironic) - that a lot of great insight is really just combining two ideas that no one has ever thought to combine before.

Something I haven't seen explored, but I think could perhaps help is to somehow introduce feedback regarding the generation into the context, based on things that are easily computed w/ other tools (like perplexity). In "thinking" models we see a lot of emerging behaviour like "perhaps I should, but wait, this seems wrong", etc. Perhaps adding some signals at regular? intervals could help in surfacing the correct patterns when they are needed.

There's a podcast I listened to ~1.5 years ago, where a team used GPT2, further trained on a bunch of related papers, and used snippets + perplexity to highlight potential errors. I remember them having some good accuracy when analysed by humans. Perhaps this could work at a larger scale? (a sort of "surprise" factor)

I’m not sure we can accept the premise that LLMs haven’t made any breakthroughs. What if people aren’t giving the LLM credit when they get a breakthrough from it?

First time I got good code out of a model, I told my friends and coworkers about it. Not anymore. The way I see it, the model is a service I (or my employer) pays for. Everyone knows it’s a tool that I can use, and nobody expects me to apportion credit for whether specific ideas came from the model or me. I tell people I code with LLMs, but I don’t commit a comment saying “wow, this clever bit came from the model!”

If people are getting actual bombshell breakthroughs from LLMs, maybe they are rationally deciding to use those ideas without mentioning the LLM came up with it first.

Anyway, I still think Gwern’s suggestion of a generic idea-lab trying to churn out insights is neat. Given the resources needed to fund such an effort, I could imagine that a trading shop would be a possible place to develop such a system. Instead of looking for insights generally, you’d be looking for profitable trades. Also, I think you’d do a lot better if you have relevant experts to evaluate the promising ideas, which means that more focused efforts would be more manageable. Not comparing everything to everything, but comparing everything to stuff in the expert’s domain.

If a system like that already exists at Jane Street or something, I doubt they are going to tell us about it.

I have not yet seen AI doing a critical evaluation of data sources. AI willcontradict primary sources if the contradiction is more prevalent in the training data.

Something about the whole approach is bugged.

My pet peeve: "Unix System Resources" as explanation for the /usr directory is a term that did not exist until the turn of the millenium (rumor is that a c't journalist made it up in 1999), but AI will retcon it into the FHS (5 years earlier) or into Ritchie/Thompson/Kernigham (27 years earlier).

I also hope we have something like this. But sadly, this is not going to work. The reason is this line from the article, which is so much harder that it looks:

> and a critic model filters the results for genuinely valuable ideas.

In fact, people have tryied this idea. And if you use a LLM or anything similar as the critic, the performance of the model actually degrades in this process. As the LLM tries too hard to satisfy the critic, and the critic itself is far from a good reasoner.

So the reason that we don't hear too much about this idea is not that nobody tried it. But that they tried, and it didn't work, and people are reluctant to publish about something which does not work.
