Artificial Intelligence

We live in an age of dishwashers, microwaves and mobile telephones, in an age where chairs can recline, doors can open automatically and some knives can cut through shoes, and in an age where computers are now so powerful that they can beat people at chess. However here is probably the best reason I’ve heard why man will always have the edge over any form of artificial intelligence:

"Man is the best computer we can put aboard a spacecraft - and the only one that can be mass produced with unskilled labor." 
Wernher von Braun (engineer and pioneering rocket scientist)
