From the BBC:
A master player of the Chinese strategy game Go has decided to retire, due to the rise of artificial intelligence that "cannot be defeated".
Lee Se-dol is the only human to ever beat the AlphaGo software developed by Google's sister company Deepmind. In 2016, he took part in a five-match showdown against AlphaGo, losing four times but beating the computer once.
The South Korean said he had decided to retire after realising: "I'm not at the top even if I become the number one. There is an entity that cannot be defeated*," the 18-time world Go champion told South Korea's Yonhap news agency.
Depressing either because AI is now cleverer than we are - or because Go wasn't as difficult as people thought.
* Presumably, sooner or later they will develop a new programme that can beat AlphaGo, but that's probably not what he meant.
