Lean is a lovely language ecosystem, as Tao clearly demonstrates though, LLMs can struggle with it. The language and the tooling is designed heavily around not merely text code, but continuous feedback from a specialized shell, though Tao attributes the issue to another condition, that there are two acutely similar versions of the language.
Slightly offtopic, but there are other Fields Medalists on youtube too, such as Richard E Borcherds. He has some very nice videos on number theory and abstract algebra.
