It seems that rudimentary artificial intelligence has figured out and implemented what we mere humans have yet to do. They figured out how to live in peace with each other.
This screen grab from a forum (from a retweet by William Gibson) tells the story. In short, after running a Quake 3 bot simulation for four years, all 16 bots learned that the best way for individual survival is for each individual to stop initiating aggression. The secondary result is collective survival as well.
