My take: 1. It shows what even this wave of AI can actually do. 2. I wish it were done by different folks, ideally under some kind of public control like NASA research or the NPR model. 3. Keep in mind: natural science is different. It's not always a matter of computation. Computer science folks often struggle with this -- but this virtual world here does not actually exist.

"Our work is so much harder than their work that AI now does" is a refrain of the AI story. In technical terms you concern can be stated as "AI needs to be much more sample-efficient to not be bottlenecked by the speed of doing experiments." People don't find out all the relevant phenomena present there by holy spirit, after all.

BTW, there's also a problem of asking interesting questions that AIs aren't yet good at.

No one has found any principled walls of AI development yet. And empirical results are quite telling. So, I guess, those problems will not stand for long.

This is undeniably epochal, but I can't help but notice that this is yet another example of AI disproving rather than proving something. Is this just a coincidence, or does AI slightly struggle with proving theorems?[0] [0] Struggle relative to its ability to disprove, not struggle relative to people's ability to prove theorems.

There has been the proof of the cycle double cover conjecture: https://news.ycombinator.com/item?id=48863490

Of course AI was involved, you'd expect most mathematicians and researchers to use AI nowadays. This drama is about AI achieving impressive outcomes with little to no human intervention, as that would be signalling AGI.

> This drama is about AI achieving impressive outcomes with little to no human intervention That's not at all what the drama is.

Of course, as any drama, it has been developing into a lot more but the main motivation for OpenAI has been about winning that battle.

Math is like this too. The big problems they've been solving have been identified as interesting only through lots of prior effort.

What happens to real fluid in this particular cases? If the singularity is in the physical space? Is this just a result of ignoring things like friction and energy dissipation via heat, etc?

Navier Stokes assumes the fluid is a continuum. The smallest scales that it effectively models [1] are larger than the mean free path of the molecules in the fluid, measured by the Knudsen number [2]. Whenever a phenomenon in the Navier Stokes equations happens in a scale on the order of or smaller than the mean free path, Navier Stokes effectively is unphysical. So, this is a phenomenon in the equation we use to model the fluid, not a physical phenomenon observed in a real fluid.

Buried under the drama is the fact that OpenAI is claiming that an internal model they’ve been training for less than two weeks is more than twice as capable in mathematics as Astra, which was only made public a week ago. Even if this improvement is limited to mathematics, that is an astounding feat.

Brain has loops and parallel connections.

Loops and parallel connections make transformer go brrr

They are highly capable, no doubt about that, but: 1) We don't really know how they arrived to this result except that they had a lead and that they threw millions of compute at the problem.

1) The article is written in a way that states clearly they threw a lot of compute at the problem.

Did I say otherwise?

> 2) Millenium Problems have been the goal every AI company wanted to achieve since their diffusion, all companies have thrown a lot of resource to solve these problems, as they are very famous and scientists spent a lot of time trying to solve them. The first company to solve it will remain in history, despite all of you finding excuses about it.

I know, but I don't know how that relates to my point, which is about the way they are doing it.

The ROI is probably billions of increased pre IPO valuation.

The ROI is billions added to their valuation. Also of course it costs OpenAI much less than API pricing for inference.
