Computer simulations are sometimes hilarious. Remember that 1960's Vietnam War anecdote?
“There’s the old apocryphal story that in 1967, they went to the basement of the Pentagon, when the mainframe computers took up the whole basement, and they put on the old punch cards everything you could quantify. Numbers of ships, numbers of tanks, numbers of helicopters, artillery, machine gun, ammo—everything you could quantify,” says James Willbanks, the chair of military history at U.S. Army Command and General Staff College. “They put it in the hopper and said, ‘When will we win in Vietnam?’ They went away on Friday and the thing ground away all weekend. [They] came back on Monday and there was one card in the output tray. And it said, 'You won in 1965.’”
