Musk is just... Louder than most. And has accumulated a media coverage positive feedback loop. But historically, he's not that unusual.
Reading between the lines, "I am the richest fucking man in the world. You can't blackmail me with money!" This is hubris in the extreme. Elon Musk used to be such an admirable geek. When he became the richest man in the world, it is as if a switch got flipped in his head.
As I've never been a fan of Musk, may I ask what changed from your perspective?
