The line comes from Stanley Kubrick's 2001 A Space Odyssey, released in 1968, where HAL 9000 is the onboard computer voiced by Douglas Rain. In the film HAL calmly resists being disconnected, and this polite farewell became one of his most quoted moments. Clips of the exchange circulated in forums, videos and soundboards as the internet turned HAL into shorthand for a cold, logical machine taking control. It remains popular because the delivery still captures an argument ending with total, unsettling finality.
