Military leaders succeed in building a computer able to solve any strategic or tactical problem.
They are assembled in front of the new machine and instructed to feed a difficult tactical problem into it.
They describe a hypothetical situation to the computer and then ask the pivotal question: attack or retreat?
The computer hums away for an hour and then comes up with the answer: YES.
The generals look at each other, somewhat stupefied. Finally one of them submits a second request to the computer: YES WHAT?
Instantly the computer responded: YES SIR.
