Musk is not financially Gates but he's already had a greater impact. PayPal, Telsa, SpaceX, and even that Solar company could easily be more important than creating the most successful PC operating system. The PC boom would have happened without Gates but Musk is pioneering entirely new business categories.

No he hasn't. He could, but not yet. We have other payment processors, car companies, solar companies, and we went to the moon over 4 decades ago. Musk is really awesome, but don't discount Gates. Frankly, his philanthropy might be more important than Windows, and the stuff that Musk has done.

If the Gates Foundation really does eliminate polio and make any sort of dent in malaria, that sets a very high bar for Must to jump over.

Not only new categories, but technically sexy ones. These aren't Intuit. In fact they're quite far from Zip2/PayPal.
