Ultimately, it wasn't enough. Now, even though AlphaGo isn't officially ranked as a Go player, we pretty much have to admit that an artificial intelligence has surpassed human skill at this game.
。

AlphaGo made headlines when it won against legendary Go player and multiple world champion Lee Sedol (currently ranked number 7) in 2016, with a score of 4:1. It also won against European champion Fan Hui in 2015, with a 5:0 score. Before this, it was generally thought that AI couldn't compete in Go at the highest level due to the game's complexity.。

The tournament lasts for two more days; on May 26, AlphaGo will participate in a pair match, combining its abilities with human players, as well as a team tournament in which it will try to win five seasoned players at once.。
