AI is outcounterexampleing human mathematicians in real time (with Lean formalization)
“AI solved a 100-year conjecture during the World Cup final, spat out a perfect Lean proof, and mathematicians are calling each other crazy for using it.”
Why It Matters
Concrete artifact (blog timeline + PRs + "crazy" professor emails) showing AI shifting math from human proof-writing to interpreting alien machine-generated counterexamples and formalizations; future-shock for builders in formal methods/science (PhDs now need $200/mo AI tools; humans become insight curators). Darkly funny "wow" moments and overload risks fit mischievous tone.
Evidence
Xenaproject.wordpress.com post (July 20, 2026) detailing specific cases (ChatGPT disproving Erdős unit distance conjecture; OpenAI's Sol generating 1.2M lines of Lean code; Anthropic's Claude Fable finding counterexamples to Grothendieck group schemes and Jacobian conjecture "during the 2026 World Cup Final," formalized in ~1k lines and PR'd to mathlib/DeepMind repos); strong X buzz (e.g., mathematician post on job evaporation with 267 likes, replies debating "evaporating hundreds of years of labor").
