AFAIK, the guy has had a marvelous and productive career. When he says "...knowing Lisp destroyed my programming career" he just means that at some point in time he switched to other things. There was no "destruction". It was "a pivot"-- to use HN lingo. I think anyone who makes programming (let alone programming in a particular tool/language) the absolute focus of their career is in for a major disappointment. The OP was NOT crushed by his realization. He just moved on and appears to have been very successful regardless. Not a big deal unless one is obsessed with Lisp.
