First to create a workable, marketable, functional-in-the-real-world electric cars and created the first new successful car company in the US in decades to design, build, and sell them. Designed and built reusable rockets that run good reliably to the ISS for a fraction of the cost of any other solution ever devised by man. Also working towards sending people to Mars, which even world governments haven't even seriously considered. And on the Solar City side, they're making solar power so affordable to people that they've become the number 1 installer for residences in the US and the number 2 installer overall in less than 10 years of existence. 4.3 gigawatts of power produced by their installations as of 2013. They're doing all this while bumping up US manufacturing to compete directly with the Chinese. Who else is doing that successfully?
And again, I ask, what have YOU done lately besides read Wikipedia and spout off about things you don't understand? Because Musk, the guy you're criticizing, seems to be busy getting shit done.
