Michio Kaku: All I’m saying is there is vast uncertainties in projecting Moore’s law into the future. However, I would say by end of the century it is definitely conceivable that if we work out the technical problems we might be able to create machines that are as smart as us. Right now our machines are as smart as insects. Eventually they’ll be smart as mice. After that they’ll be smart as dogs and cats. Probably by the end of the century, who knows, they’ll be as smart as monkeys. At that point they could become potentially dangerous because monkeys can formulate their own plans. They don’t have to listen to you. They can formulate their own strategies, their own goals and I would say therefore at that point let’s put a chip in their brain to shut them off if they get murderous thoughts. Isaac Asimov advocated something like that with his "Three Laws." I say hey, put a chip in their brain to shut them off if they start to get murderous.
