And don't forget our buddy Leonardo Da Vinci, who designed and built a robot knight circa 1495, and showed him off at a celebration hosted by some duke.
They rediscovered those books of his in the 50's, and built the robot according to specifications, and surprise surprise, it works.
Also, he wasn't entirely off with the cars. There ARE Electric cars. And they ARE becoming more commonplace. Only thing is the oil companies are just too big to bu pushed away so quickly or so easily. The Oil companies are the reason that Electric cars are not more mainstream.
US being bombed wasnt off either, the WTC had a bomb set off in it's parking lot in '93.
