For 87 years, the Jacobian conjecture stood as one of mathematics' quiet monuments to human limitation — a question about polynomial mappings posed in 1939 that generations of brilliant minds could not resolve. This summer, Anthropic's Claude Fable 5 produced a concrete counterexample in hours, formally disproving the conjecture and marking a moment when the boundary between human and machine insight shifted in ways the field is only beginning to reckon with. The result is not a simulation of understanding — it is verifiable, peer-reviewable mathematics, and it raises the oldest of questions i
