Outcome

Accurate

An independent end-of-2025 review of AI predictions rated this correct: AI could perhaps pass the novel reading-comprehension task, but no system could do any 4 of the 10 tasks (e.g. 10,000+ lines of bug-free code, Pulitzer-caliber books, formalizing arbitrary proofs). Marcus's own December 2025 review says the same.
