I support Artificial intelligence because of the possibility of it being really helpful, that it remembers everything and it tries to do what you tell them to do, something like that but I think there would be no chance of them taking over (like the terminator or something) if there are precautions that cannot be written over by the system or something.
People are such fools that some hacker can get into the code and change it. Then there can be trouble. But to be honest it seems to me that man will destroy the planet than Artificial intelligence. Man is the most aggressive and the most stupid creature on the planet.
