I think the Tesla's are cool, SpaceX is immpressive, I enjoy his online trolling but I don't think he is a genius. The rocket scientist he employs at SpaceX is a genius. I got caught up on the way you phrased your response-- I felt that it was written in bad faith with "he's just an engineer who had a very rich father, Did he invent something that I'm not aware of? ". However seing as you were responding to someone who elevated him to Genius I can see why.
