In 2015 artificial intelligence simulated every possible game of chess; all 10^120 possible games. Before that you could play chess with your friends and reasonable assume that this chess game will be different to all other chess games ever played. Now, alot of the fun is taken away knowing that some computer simulated all possible games and your game is not unique. How long will it be before artificial intelligence can simulate all possible games in a game like Super Mario Bros, how about modern games that are even more complex?
