He buys companies and lets the actually competent people do the work while claiming credit.
No he doesn’t. He meddles and interferes constantly and convinces himself that he’s adding value by doing so. That’s why Neuralink is dangerous. Meta or Alphabet or Microsoft or whoever can be trusted to let the scientists and the legal team ensure there’s very little risk of everything blowing up in their face horribly. Elon’s little empire is constantly on the verge of an absolute disaster. I would not be remotely surprised if Neuralink messes everything up so much that it sets back brain implants and BCI’s in general by decades. Purely because Elon can’t just supply the people at his businesses with the tools they need then get out of their way.
It’s slightly different when you show consumers you’re willing to screw them out of nowhere than when you show businesses that you’ll do so. People shake that stuff off as an annoyance because they aren’t dependant on those businesses behaving decently in order for them to keep the lights on. When a partner shows it could randomly kill your business at any moment for no good reason, you tend to realise the importance of disengaging from them.
I wouldn’t trust a sandwich made by one of his companies.
