A bot could be the best new Dota 2 player in the world. At the Valve’s yearly Dota 2 tournament last night, an AI from Elon Musk-backed startup – OpenAI – defeated the Dota 2 pros in a 1 vs. 1 match. The bot learned enough in just two weeks of real-time to achieve that and amassed “lifetimes” of experience.

Elon Musk on Twitter hails the achievement as it’s the first time artificial intelligence has been able to beat pros in competitive e-sports.

Though the demonstration was limited to just a few variables of game-play, but it was remarkable to witness the Dota 2 pro, Danylo “Dendi” Ishutin get crushed in a 1-vs-1 match. Dendi, after being defeated by the bot twice, expressed surprise that a bot could outplay a human. He said the bot “feels a little like human, but a little like something else.”

Musk founded OpenAI as a nonprofit venture to prevent AI from destroying the world. But at least for now, the AI seems limited to parlor tricks at e-sports tournaments. The next plan for the OpenAI team is to extend Dota 2 bot’s capabilities and to make it compete across the full game in a 5-vs-5 match by next year’s tournament.
