I am in the top 3% but I don't know if that means a lot or not much :-/

I have always maintained that real mathematics starts when you address the infinite. I don't see how you can get anything interesting (like analysis, differential geometry, topology) without the assumption that the infinite exists.

BTW, the article is really badly written.

> uutils now runs the upstream GNU coreutils test suite against itself in CI. That’s the right scale of defense for this class of bug. That's the minimum, it is absurd that they did not start from that!

The article is badly written. This has nothing to do with fractals, they are talking about the assumption that there is an UV fixed point for all physical laws, which can even be true and personally like. It means there are no ultraviolet divergences and that at some point quantum field theory becomes finite. Over a certain large mass scale (which still can be much smaller than the Plank scale) all the coupling constants freeze, there are no radiative corrections and all is simple and well behaved. The problem is, you need some extra fields to do that, with some symmetry cancelling the divergences over the mass scale (it does not have to be supersymmetry) and we lack a theory for that. Moreover, the low energy physics will be nearly independent from the high energy modifications, so the predictive power is low. Yes, they predicted the Higgs mass, but it could very well be a coincidence. If they could predict something really new, though, then it would become quite interesting.

As a former Theoretical Physicist, this result is remarkable. I myself I tried to use AI for calculations in Perturbative Quantum Field Theory and I was impressed. I agree with the authors: it looks like the future of Theoretical Physics would be more in verification and consistency checking of AI-assisted results rather than in manual calculations.

My barber is 75+ and he says that he has no intention of ever retiring, until he is forced to by health reasons.

I like far-future concept-driven science fiction, is there something for me too?
