You put your finger on why I felt compelled to unfollow PG on Twitter. I kept waiting for him to hit me with valuable insights that rarely showed up. I took the time to learn Lisp because of PG and was underwhelmed. I bet Lisp was amazing 40 years ago; now it just seemed like a fetish for parenthesis to me. Lispy and functional ideas have moved into the brace block languages I've been using the last 20 years.
