AI verifies the 15,000-page finite simple groups classification in 24 days with 50M lines of Lean

An AI reportedly formalized the finite simple groups classification theorem—a body of work that took humans half a century and 15,000 pages—in 24 days using 50 million lines of Lean code, also fixing a gap in the original proof. The author argues AI intelligence has surpassed humans, that paradigm breakthroughs compound into broad change, and that the real skill now is being a good reviewer and orchestrating agents well: 'those who use fire became homo sapiens.'
