I think it's important to remember that musk has never actually done anything to innovate the companies he's been a part of. He didn't create PayPal, he just bought his way in and made a series of dumb suggestions. He didn't create Tesla, he bought Tesla right after they had fine tuned their models, and then he made a series of changes that likely resulted in a worse product.
Elon Musk is not a good businessman, he's just rich and has a habit of purchasing profitable companies. Anyone could do this with his wealth. I'm not even really convinced that he's offered many technical ideas or designs for any of his companies, as it seems that would be the first thing he would mention every single time someone brought up one of his companies.
