One of the most interesting aspects of
@leanprover's rise, as I came to understand it writing The Proof in the Code, is the degree to which chance events and small encounters changed its course:
*Johan Commelin walking along the side of the road in Princeton
*Kevin Buzzard tuning into Tom Hales's lecture from his backyard shed
*Patrick Massot needing to check a student's calculation.
Another story which I didn't get to include in the book is
@TaliaRinger emailing Terry Tao, which turned into meeting for coffee in the summer of 2023, which turned into a multi-hour chat about the potential for Lean and other systems to facilitate large-scale collaborationsโthe kind that are common in other fields but rare in math (and would later be realized with the equational theories project).
As Talia wrote later in the Notices of the
@amermathsoc, "In the futuristic world we live in, when you submit a pull request to Terry Taoโs GitHub repository, you do not need to worry much about accidentally breaking his proofsโno matter who you are."
