"Is math discovered or invented?" is a question that underlies a lot of math philosophy writings I've read (of the popular science variety) and so I could immediately understand where Lex was going with it. It is a simple question which can elicit as much depth one is willing to dive into. Similarly I thought all of Lex's questions came from deep understanding of what he was asking, and he would've known clearly what Sanderson would've replied (minus his personal insights) and what other competing answers are out there. I love Lex Friedman's interviews - he simply asks a small but fertile question and then lets the guest talk.
