Glad I'm not the only one. I'm 90 minutes in and finding some of Lex's questions really bad. Especially "What is the best programming language?", but I'm also astonished that Lex doesn't seem to know what an x86 is, hasn't really heard of Pascal, and was incredulous that anyone could write a game in assembly language (but as Carmack points out, everyone in the 80s was writing games in assembly, BASIC just wasn't fast enough).
Maybe Lex was trying to dumb things down for a non-technical (or younger?) viewer, but it doesn't come across that way and just interrupts Carmack's flow. Carmack is excellent though.
