HAL 9000 (2001: A Space Odyssey)

To kick things off, we have to talk about one of the most terrifying sentient bots of all—the “Heuristically programmed ALgorithmic Computer,” or HAL—from Stanley Kubrick’s 1968 film 2001, A Space Odyssey. And by design, he’s a pretty hard working bot: he’s built into the spacecraft where the film takes place, and is tasked with essentially running the ship. He opens doors, keeps life support systems afloat, and, like LaMDA, he can talk.
Unlike LaMDA though, HAL comes programmed with real, human emotions. And after encountering a minor glitch at the start of the film, those emotions are what cause HAL to go off the rails (to put it mildly).
“Most advanced computer theorists believe that once you have a computer which is more intelligent than man and capable of learning by experience, it’s inevitable that it will develop an equivalent range of emotional reactions—fear, love, hate, envy, etc,” Kubrick said about the bot in an interview. “Such a machine could eventually become as incomprehensible as a human being, and could, of course, have a nervous breakdown—as HAL did in the film.”
