Can AI conquer Fermat's last theorem? Mathematician gave up 5 years of his career to turn 100 pages of proof into code Can AI conquer Fermat's last theorem? Mathematician gave up 5 years of his career to turn 100 pages of proof into code Apr 09, 2024 pm 03:20 PM

Fermat's last theorem, about to be conquered by AI? And the most meaningful part of the whole thing is that Fermat’s Last Theorem, which AI is about to solve, is precisely to prove that AI is useless. Once upon a time, mathematics belonged to the realm of pure human intelligence; now, this territory is being deciphered and trampled by advanced algorithms. Image Fermat's Last Theorem is a "notorious" puzzle that has puzzled mathematicians for centuries. It was proven in 1993, and now mathematicians have a big plan: to recreate the proof using computers. They hope that any logical errors in this version of the proof can be checked by a computer.
