Badly behaved artificial intelligence (AI) systems have a long history in science fiction. Way back in 1961, in the famous Astro Boy comics by Osamu Tezuka, a clone of a popular robot magician was reprogrammed into a super-powered thief. In the 1968 film "2001: A Space Odyssey," the shipboard computer HAL 9000 turns out to be more sinister than the astronauts on board think.
