Recently I watched how a fairly fast developing OpenAI managed to get more than a basic grasp at a co-op game - DotA 2.
Last year, they've shown one hero AI, being able to beat consistently with high rate top human players. Now, while still with significant restrictions, they managed to make 5 AI bots co-operate in a team game and beat 5 men team of really good players (retired pros).
I wonder, how could this affect gaming. I mean, we often hear complains how AI is bad in this or that game, etc., but think of a scenario, where AI will beat average player 99.9999999999999% times, and the best human player 90% of the time. Where is the limit for an enjoyable, yet challenging AI in games, which would be playing by the same rules and with same resources, and where the good AI becomes too good for a game to be fun (no one wants loosing all the time, even though you know the conditions are fair)
