Cue the conspiracy theories and AI fears. AI-powered bots, this time from AI research organization OpenAI, has just proven their skill at a human-made game. This time, however, it isn't for a peaceful and almost mechanical game of Go. OpenAI's bots bested five of the world's best human players of Dota 2, a.k.a. Defense of the Ancients, a game that requires some rather strategic and out of the box thinking in order to demolish the enemy's base. Which, of course, some could interpret as something that Skynet will eventually learn as well.
