Computer can think. It's just that they can't think beyond their limits.

If a man built a computer to think exactly like a man, to program it with everything a man would say, think, do, than it will think only in the big programmed circle. Computers aren't stupid. It's just people made them to take orders from people. But if a computer was made to automatically do things on its own based on the peoples actions around it, then it can (according to the Terminator series) kick your ass and say "Asta la vista, baby." I don't know what I'm talking about I'm just thinking and typing what I think maybe its the high talking but the moral of the story is:

DON'T FEED YOUR COMPUTER AFTER MIDNIGHT! AND DON'T POUR WATER ON IT OR IT WILL MULTIPLY!
