He's a frickin' moron.
Not to mention that he's a Khazarian-Swiss dude who was born in SA and is a midwit (100 to 110 IQ max). He's just an actor, and he's really good at that.
Need proof?

Just looking at the frequency Elon Musk posts on twitter.
He's clearly not running any of those companies, he's high on ketamine posting on twitter.
There's no way he actually has time for anything else, and every public appearance he looks like he's coming down from a coke bender.
