Did Elon Musk's AI champ destroy humans at video games? It's complicated

You might not have noticed, but over the weekend a little coup took place. On Friday night, in front of a crowd of thousands, an AI bot beat a professional human player at Dota 2 -- one of the world's most popular video games. The human champ, the affable Danil "Dendi" Ishutin, threw in the towel after being killed three times, saying he couldn't beat the unstoppable bot. "It feels a little bit like human," said Dendi. The bot's patron was none other than tech billionaire Elon Musk, who helped found and fund the institution that designed it, OpenAI.
