I just found out about Elon Musk a couple of weeks ago and I'm really linking this guy. I feel like he actually wants to revolutionize humanity into the next generation with a bunch of different companies. SpaceX is experimenting amazing stuff, and this Tesla stuff is equally awesome. He also has been hinting about a 'fifth mode of transportation' that he's calling Hyperloop, which if you haven't heard about it you should read about it cause it's really cool and revolutionary. He also had an interview with TED. LINK
That means he's good at it. There's a Tesla dealership up in Santa Monica. SpaceX is just down the street. I wish the dude well. I don't think he's a genius, though, I think he's a motivated entrepreneur with skills and heart. I would have said the same thing about Gates and Allan 20-30 years ago.
I've heard him make the joke, "how do you make a small fortune in Space Travel? Start with a large one." -Old joke but likely true in this case.
