What "heavy-duty" software did Musk write for a 20 year period? I can't square it with the career section in his Wikipedia bio.
Is he writing any software at SpaceX or Tesla? I've heard stories here and there of him sitting in an engineering meeting.
Zip2 was founded in 1995 -- there are credible claims (from a biography) he wrote software there, and that's all I've found.
When I see him talk about AI (which he claims to be an expert in), it’s like hearing college freshman, after first 5 classes of ML 101, who read a lot of pop-science blogs about it.
