Is an amazing guy. He went to Stanford for a Ph.D in physics but dropped out after two days to start Zip2 where he made his first millions. He then leveraged his economics degree to found X.com which led to the creation of Paypal where he made some millions more. He went on to found SpaceX that now supplies the ISS (not to be confused with ISIS). Tesla is possibly his most visible creation with cars appearing on the roads every day.
He is now working on even more ambitious projects.
I find it funny that some here feel his implosion is imminent. I guess Bill Gates is right behind him.
