Not everyone is convinced that such narrow utility is the ultimate horizon for AI, of course. Pollack says many researchers still dream of the humanlike robot. And if we ever do get to that point, the movies have provided us with a few helpful warnings. For example, fathers will need to keep their eyes peeled for robotic suitors. In Bicentennial Man, unsuspecting parents purchase a household robot for domestic chores, only to have their daughter fall for it. This is an unsettling prospect, but Gigolo Joe, the robotic male prostitute played by Jude Law in AI, is even more frightening. Beyond his superior physical endowments, he's programmed to always say the right things. That's hard to compete with. Another rule is to always check your AI for homicidal tendencies. The voice is a particularly good giveaway. If it sounds anything like HAL, it's either low on batteries, high or evil. And if Stealth is any indication, it's probably not a good idea to give our AIs too many weapons, either.
