HAL 9000

""I'm sorry, Dave. I'm afraid I can't do that.""

- HAL 9000

The HAL 9000 was the main villain of 2001: A Space Odyssey. It was an incredibly knowledgeable AI system that was given one simple order: Make sure that the ship reached its destination at Saturn. But when the ship became unsafe for the human crew, they resolved to go back for more supplies and fix the problems with the ship. HAL couldn't let that happen, so it convinced the crew to go out into space and fix one of the broken appendages on the ship. When they did, HAL sealed the air lock and the astronauts died in hard space. Only two of them survived. The two survivors went into an area of the ship where HAL couldn't monitor them with speakers. Undetered, HAL read their lips. Luring one astronaut into the airlock, it sent him into the void of space. All that was left was Colonel Dave. Seeing Dave still alive, HAL turned off the gravity and oxygen. But Dave found an oxygen tank and finally managed to float his way into HAL's central processing unit and disabled his AI unit. HAL went out singing the song he was taught when he was first activated: "Daisy."
