Daisy Bell was written by Harry Dacre in 1892 and became one of the most famous songs of its era. It entered computing history in 1961, when an IBM 7094 became the first computer to sing, performing Daisy Bell with programmed accompaniment. The moment was later echoed in Stanley Kubrick's 2001: A Space Odyssey, where HAL 9000 sings the same song as it is shut down. That film connection keeps the tune tied to artificial intelligence, and online creators still reuse the robotic version for jokes about machines, robots and outdated technology.
