OpenAI's Dota 2 defeat is still a win for artificial intelligence

Last week, humanity struck back against the machines -- sort of. Actually, we beat them at a video game. In a best-of-three match, two teams of pro gamers overcame a squad of AI bots that were created by the Elon Musk-founded research lab OpenAI. The competitors were playing Dota 2, a phenomenally popular and complex battle arena game. But the match was also something of a litmus test for artificial intelligence: the latest high-profile measure of our ambition to create machines that can out-think us. In the human-AI scorecard, artificial intelligence has racked up some big wins recently.
