I don't know why you guys are all up on Tesla's cock. He did some cool shit, basically invented AC current, but he really didnt do nearly as much as Einstein, Da Vinci, or Galileo. Kind of a one trick pony, who was working with pretty useless and obscure science at the time.
He kind of is the scientist of where we are, I see Einstein as the mind that could see where we're going. Hawking is also up there, a lot of people see him as a celebrity scientist, like Bill Nye, but he has done some serious groundbreaking shit, especially with his newest black hole theory.
Space is the future, not AC currents. Tesla was just a building block.
