On the topic of robots replacing humans....
In this story they replaced humans for a violent sport (boxing)
However, recently a computer beat a professional GO player for the first time, never before could a computer beat a professional at that famous abstract strategy board game.
I am absolutely fascinated by board games, I even have designed some. Imagine a setup where different computer programmers set their computers against each other to play world class strategy games. That would fascinated me. If not in a movie maybe it should happen in real life?
