One of South Korea‘s most acclaimed able Go players, master Lee Se-dol, has retired, citing the futility of raging adjoin the machines as a affective factor.

Speaking to reporters from the Yonhap News Agency in Seoul beforehand this week, Se-dol said:

With the debut of AI in Go games, I’ve accomplished that I’m not at the top even if I become the number one through agitated efforts. Even if I become the number one, there is an entity that cannot be defeated.

Se-dol’s 24-year career includes wins over dozens of the world’s top players, including a stint as world champion. He faced DeepMind’s AlphaGo in five matches during March of 2016 where he managed to come away with just a single win. Prior to the bouts, Se-dol predicted he’d win by “a landslide,” and by all letters he was apace abashed when the AI again beat him.

Still, Se-dol charcoal the only player to date to have beaten AlphaGo in erect official clash play. This makes his retirement all the more awkward — he’s one of the only humans on the planet able of going toe-to-toe with the machine.

It’s worth pointing out that Yonhap News Agency added letters Se-dol’s retirement was also accompanying to an advancing legal dispute:

Lee didn’t deny that his retirement accommodation was also afflicted by a battle with the KBA over the use of associates fees. He absolutely quit the KBA in May 2016 and is now suing the affiliation for the return of his associates fee.

When we think about AI abolition industry and displacing workers we usually accede factories and farmers. But here, we see affirmation that the rise of AI has a potentially annoyance effect on human competitiveness at the elite, world-class level. That’s absolutely some cause for concern.
