Recent LLM dingers like the Jacobian Conjecture counterexample have challenged the efficient mathematics hypothesis. The JC counterexample was so small in degree and coefficient. It should have been a "low fruit" in the scheme of things, but alas, unpicked for 50+ years with considerable attention from good mathematicians.
With respect to FLT, my hopes have modestly increased that a truly marvelous demonstration of this proposition does in fact exist, that Fermat actually had it, and that it may someday be recovered!
edit: some emphasis on modest. But let me be romantic here!
This is the most offensively-themed serious site I have ever seen.
I have a truly marvellous comment on this, which this comment box is too small to contain.
From 2000.

This was an excellent introduction to this topic:

But I am not sure if the book covers the mistake and later correction. I has been more than a decade sine I read the book (and became a fan of the author).
