Many scholars dispute the likelihood of unanticipated cybernetic revolt as depicted in science fiction such as "The Matrix", arguing that it is more likely that any artificial intelligence powerful enough to threaten humanity would probably be programmed not to attack it. Pinker acknowledges the possibility of deliberate "bad actors", but states that in the absence of bad actors, unanticipated accidents are not a significant threat; Pinker argues that a culture of engineering safety will prevent AI researchers from unleashing malign superintelligence on accident. In contrast, Yudkowsky argues that humanity is less likely to be threatened by deliberately aggressive AIs than by AIs which were programmed such that their goals are unintentionally incompatible with human survival or well-being (as in the film "I, Robot" and in the short story "The Evitable Conflict"). Omohundro suggests that present-day automation systems are not designed for safety and that AIs may blindly optimize narrow utility functions (say, playing chess at all costs), leading them to seek self-preservation and elimination of obstacles, including humans who might turn them off.
