War Games.

This footage made me think of the 80s movie War Games:

Joshua: Shall we play a game?
David Lightman: Oh!
Jennifer: [giggles] I think it missed him.
David Lightman: Yeah. Weird isn't it?
Jennifer: Yeah.
David Lightman: [typing] Love to. How about Global Thermonuclear War?
Joshua: Wouldn't you prefer a nice game of chess?
[Jennifer laughs]
David Lightman: [typing] Later. Let's play Global Thermonuclear War.
Joshua: Fine.
...
David Lightman: [typing] What is the primary goal?
Joshua: You should know, Professor. You programmed me.
David Lightman: Oh, come on.
David Lightman: [typing] What is the primary goal?
Joshua: To win the game.
...
David Lightman: [to Joshua] Come on. Learn, goddammit.

[after playing out all possible outcomes for Global Thermonuclear War]
Joshua: Greetings, Professor Falken.
Stephen Falken: Hello, Joshua.
Joshua: A strange game. The only winning move is not to play. How about a nice game of chess?
