There are many iconic moments in Stanley Kubrick's 2001: A Space Odyssey, but the part of the movie that receives the most attention is the segment revolving around HAL, his malfunctions, and his final song, "Daisy." HAL is the artificial intelligence system for the HAL 9000 computer that controls the Discovery One spacecraft, and he is generally considered a trusted member of the crew until he begins to malfunction. These glitches result in the deaths of multiple crew members and the decision to shut HAL down. In the latter moment, the sentient computer begs for its life.
