It's a decades-old geek joke that the perfect computer would only have one instruction: Do What I Want. In The Future, this will be achieved, so that a character can push the same button over and over and have it do something different each time. (Often a Big Red Button, but not always) This is most commonly the result of a set constructed with lots of control panels, but no one keeping track of which button serves which purpose in the context of the story. These are often used to control the Do-Anything Robot. Compare Action Commands, Green Lantern Ring, Magic Tool, Damn You, Muscle Memory!.
