Terence Tao Explains The Math Behind AI

Terence Tao has read more mathematics than almost anyone alive, and he uses AI tools every day. So when one of the most cited mathematicians on Earth says these systems still can't ask a genuinely new question, it's worth understanding exactly where he draws the line — because it isn't where the headlines put it. Watch the full conversation: https://youtu.be/ukpCHo5v-Gc If AI has absorbed every textbook ever written, why can't it discover anything new? Tao, a Fields Medal winner and professor at UCLA, separates what these systems do brilliantly from what they can't do at all, and the boundary turns out to be sharper and stranger than most people assume. We cover why reproducing a famous proof is less impressive than it sounds, what a neural network found hidden inside a million knots that humans had missed, why we still can't predict which tasks AI will actually be good at, the "Keating Test" — the benchmark that would actually demonstrate machine thought — and where exhaustive recall ends and real conceptual origination begins. AI can pass every exam. It just can't ask a question nobody has asked before — yet.
