TFA isn't about AI; it's about taking the same arguments mathematicians are already writing down semi-formally with a hand-wavy argument that it could be made completely formal, and instead/also writing them down formally.

In cases where the Hilbert machine applies, the mathematician writing down the semi-formal argument already has to state the new axioms, justify them, and reason about how they apply, and the proposal would just take that "reason about how they apply" step and write it in a computer-verifiable way.

This article makes me very happy.

One of the many reasons I love math is the feeling I've always had that with it, we're building skyscraper-sized mental structures that are built on provably indestructible foundations.

With the advent of "modern" proofs, which involve large teams of Mathematicians who produce proof that are multiple hundreds of pages long and only understandable by a very, very tiny sliver of humanity (with the extreme case of Shinichi Mochizuki [1] where N=1), I honestly felt that math had lost its way.

Examples: graph coloring theorem, Fermat's last theorem, finite group classification theorem ... all of them with gigantic proofs, out of reach of most casual observers.

And lo and behold, someone found shaky stuff in a long proof, what a surprise.

But it looks like some Mathematicians feel the same way I do and have decided to do something about it by relying on the computers. Way to go guys !

This hurts my engineer-brain. Just a reminder than the gap between us and mathematicians is about the same as the gap between us and everybody else (edit: in terms of math skills), just in the other direction, haha. Oh well, hopefully when they get the machines to solve math, they’ll still want them to run a couple percents faster every year.

Who likely underestimated how hard it would be.

And who didn't have a 2024 computer on hand.

My bet: there is a very long list of skills for which the gap between you and a person randomly picked out the whole population is very large, and not in the direction you seem to think.

Earlier quoted context omitted.

Compilers have this very same habit!

Yes. In fact, Lean is a compiler and type checkers are theorem provers (by the Curry-Howard correspondence). Proofs are programs!

And Mathematics is Computer Science. Took me most of a lifetime to realize this.

While it's true that mathematics cannot ever be completely formalized, per Gödel's incompleteness theorems, a huge amount of it obviously can, as is demonstrated by the fact that we can write it down in a reasonably rigorous way in a combination of conventional mathematical notation and plain English.

Nor is this in any way "a fundamental problem with using AI to do math".
