In the DOCTOR WHO serial, "Destiny of the Daleks," the Daleks and their android enemies, the Movellans, are locked in a thousand-years war. They have reached a logic impasse. A stalemate. Both sides have enormous battle-fleets waiting to strike, while their computers calculate the precise moment to attack that will grant maximum potential for victory.
They've been waiting for centuries.
The Doctor knows how to break the stalemate.
One side needs to turn OFF their computers.
I think about that solution a lot lately.
