Written in 1892 by British songwriter Harry Dacre, Daisy Bell became one of the most recognisable popular songs of its era. It entered technology history in 1961 when an IBM 7094 at Bell Labs became the first computer to sing, performing this song. Arthur C. Clarke heard that demonstration and later, with Stanley Kubrick, placed it in 2001: A Space Odyssey in 1968, where HAL 9000 sings it while being disconnected. Online, that history turned a sweet love song into shorthand for fading artificial intelligence.
