Humans have improved at Go since AIs became best in the world

AIs can beat the world's best players at the board game Go but humans are starting to improve too. An analysis of millions of Go moves has found that professional players have been making better and more original game choices since Go-playing AIs overtook humans. Before 2016, AIs couldn't beat the world's best Go players. But this changed with an AI called AlphaGo developed by London-based research firm DeepMind. AlphaGo defeated multiple Go champions, including the then number one ranked human player.
