Its strange how people still think it is a coincidence that Musk founded Tesla, SpaceX, OPenAI/ChatGPT, xAI (
Was there meant to be a sarcasm tag in your post? Musk didn't found Tesla in any meaningful manner. He invested after the company had already been created. The same of the AI companies.
SpaceX may be one company he founded, after the original X/PayPal (note that he didn't found PayPal and, in fact, he had some ludicrous ideas of how the infrastructure should be changed after he came on board). Neuralink and the Boring Company: the only thing different from Musk and all the other people who had the same ideas is money, and perhaps, a lack of scruples.
Musk has used his money strategically. He had a huge advantage early on, in coming from a wealthy family. None of that makes him stupid, but it is very likely there are far more people who could have been as, or more, successful given Musk's start in life.
