Yeah, it's a very important point that he has changed, a lot. Elon Musk's trajectory is a lot like Alexander the Great's. He started off as the somewhat scrappy upstart and has become the somewhat corrupted corporate despot. His enormous success, which has been truly amazing and largely good for humanity, has led him astray. He's bought into the image of himself as a genius that can do no wrong. He's become arrogant, temperamental, and prone to impulsive behavior. Alexander became quick to kill his managers that pissed him off. Elon Musk just fires people, thankfully. Probably a lot of his problems are due to the same kind of "men [that] have always corrupted the character of kings and will never cease to ruin the interests of those who happen to be reigning" as Arrian wrote of Alexander's yes-men courtiers. My impression is that Musk is going through a severe case of burn out and this is how he's responding. And since he's got so much pressure on him there's no practical way for him to take the break he needs without risking everything.
