Correct. He didn't become a billionaire by accident.Except for Zip2, X.com (which ended up merging with PayPal). And while he's not a rocket scientist, or an automotive engineer, he did play a large part in developing Space X and Tesla. How many Apple products did Steve Jobs actually design and build? None. He was an ideas man and knew how to put together a team and get the most out of them. That's what Elon Musk does.
