A spinning wheel is not an engine, no more than a pinwheel is a turbine.
A windup toy is not a robot, no more than a top is a robot.
A slide rule is not a computer, no more than a t-square is a computer.
You are so totally wrong that it's painful.
Work expands to fill the time available. -- Cyril Northcote Parkinson, "The Economist", 1955
