It’s tempting to think that Musk is just an idiot and that he managed to achieve success by pure luck despite that… but SpaceX and Tesla are both highly successful companies. Starlink, too, though that’s obviously connected to SpaceX, and Musk was also involved with PayPal when it hit it big. So there’s obviously something that he’s doing right.
But then again, there’s Twitter. So while it’s clear that there’s some special talent that Musk has, it’s really hard to tell just what it is.
The best I can figure is that he used to be a business genius, and put actual control of SpaceX and Tesla in the hands of highly-competent people who are responsible for those companies’ continued success, and then suffered some form of brain damage that took away that gift, and so now he’s a crazy man with crazy ideas who’s destroying everything new he touches.
