What you've done here is an overgeneralization. "People who like math" and "people who like computers" are massive demographics with considerable overlap.
Maybe. But more clearly one of the most popular online.
The topic being discussed here has been addressed specifically in his mastodon posts - the pre-LLM math process was understood to be "state a proof, validate a proof" - but the real aim was the not explicit "digest the proof so we can extend to other results" - with LLM/lean making the first two a lot easier and possible to do without accomplishing the digestion into the mathematical community; so we need to add "digesting proofs (from where ever)" into the job description.
