'Proof by intimidation': AI is confidently solving 'impossible' math problems. But can it convince the world's top mathematicians?AI could soon spew out hundreds of mathematical proofs that look "right" but contain hidden flaws, or proofs so complex we can't verify them. How will we know if they're right?
