I watched the Elon Musk interview with Joe Rogan and noticed that the guy is very arrogant. He acts as if he knows everything, yet he's wrong on a lot of stuff. Whenever he's presented with information that he doesn't know he literally acts as if what you're saying is irrelevant. In the interview with Rogan he mis-quotes Carl Sagan, and then when Rogan tells him about an event he wasn't familiar with he immediately loses interest and acted as if Joe Rogan was the stupid one for knowing irrelevant things. Musk is very arrogant. He's smart, but he's not a genius. I have a feeling Musk thinks he's a lot smarter than he actually is. I wasn't impressed by him at all. He doesn't seem all that smart yet he acts like he's the world's smartest man.
