OpenAI and Alpöge-Buckmaster both leaned on Lean for Navier-Stokes claims

Lance Fortnow notes both the OpenAI and Alpöge-Buckmaster Navier-Stokes announcements leaned heavily on Lean: OpenAI fully formulated its results in Lean, while Buckmaster's team has Lean-verified proofs for three public results but held back the blowup result pending verification. The post reviews Lean's history since Leonardo de Moura's 2013 Microsoft project, its backward-compatibility pains, and big formalization projects (Hales' Kepler proof, Scholze's liquid tensor experiment), asking whether Lean is becoming a new requirement for publishing.
