Musk lead teams at the only company who can land commercial rockets and the first company to profit from making electric cars. To say he is a wealthy idiot says more about you than it does about Musk.
At this point Musk is behaving just like a twelve year old’s idea of a mega billionaire. Hyperloop, flamethrowers, self driving cars now Twitter... It’s great that he’s having fun I don’t think there is much to it than that.
