I'm starting a interview series of people working in Lean / formal methods / math formalization Tanner Duve, Member of Technical Staff at Logical Intelligence, discusses formal verification, compilers in Lean, and AI-assisted math formalization in the first episode of a new interview series. The conversation covers contributions to Mathlib and CSLib, Turing incompleteness in Lean, and the impact of AI on formal verification, with Duve sharing insights from his background as a former D1 football player. I think the topics of discussion would be of interest to a lot of people here, so I thought I'd share the first episode: Tanner Duve is a Member of Technical Staff at Logical Intelligence working on formal verification and compilers in Lean, an open-source contributor to Mathlib and CSLib, and a former D1 football player. I sat down with him for a conversation about his work and his thoughts on the future of AI-assisted math formalization.
