Mathematicians are witnessing a profound shift in their field. AI systems are now producing proofs, spotting connections between distant fields, and, in a few cases, solving problems that had stumped mathematicians for decades. The pace of progress over the past several months has raised challenging questions: What can AI systems actually do? And what happens

But the relief when I admitted to somebody that I didn’t know something was palpable. It was amazing. I came clean, and then we had a great conversation, and I actually learned something.
