Terminators did not have to be self aware or have desires to do their job, killing. They simply had to follow a set of rules. Intelligence will merely help them follow the rules when circumstances go beyond the originally coded set of conditions. The real threat of intelligent machines is the people who would use them. Not everyone with ability acts rationally and why would we expect them to use such ability correctly?
