Why did Lee Sedol, one of the world’s best ‘Go’ players, retire from the game? 

Hey I am from south korea. He actually retired cause of political matter in go organization. He just felt tired with politics. So dont waste time thinking too much. 😅😅

When Lee Sedol beat AlphaGo in the forth game with his 78th move, he became the only human player to reach 10th dan. Respect!

he now prefers Pokemon Go

Best rage quit in history

lol that’s not why he retired from go. It’s primarily related to his relationship to the Korean baduk association

Bobby Fischer also retired from the game of chess because he said people are just memorizing moves and are not being as creative.

Other than some of the details about Sedol himself, this whole video is nothing but vacuous blather.

You are making it too sensational. He went on to win every tournament he played after he lost 4/1 to the alphago

Because he had to go.

Kind of like Usain Bolt retiring because he can't win the Indy 500.

I watched the deepmind documentary, he was such a humble man in the documentary, cant believe he quit :(

Am deeply impressed by Lee Sedol who will forever be a legend in the great game of Go. I disagree that we should define ourselves by what machines are capable of because by design they are intended to vastly outperform humans. Consider the massive D-11 bulldozer, cranes, trains, and an endless list of other machines. When Lee Sedol took on AlphaGo, he wasn't playing against a single entity like a human opponent; he was taking on hundreds if not thousands of engineers and a cosmically vast computed data base.

As long as he is happy and healthy I'm happy for him and his family. He is such a nice man, it was heartbreaking to watch him struggle against alpha go. And then he did the incredible, basically super human , and beat it, and not just by a little, the program behaved like it had been hit by a freight train until it finally conceded. I know nothing about the game but his humility has taught me a lot about being human.

Now South Korea needs to come up with a go deep learning algorithm called Sedol to compete with AlphaGo.

Legendary Go player. He didn’t know what he was getting into at the time, and for him to continue to fight as hard as he did in the face of, what he must have realized were insurmountable odds, is a credit to the human spirit.

about 10 seconds are devoted to answering the question, the rest is just irrelevant rubbish

There is a Korean proverb, believed to have been handed down from China,

now, where is hikaru when we need him the most? xD

If you consider, however, the Alpha-Go/Zero/Lee computer suite of programs does not actually "understand" Go, but merely reduces it down to a refined database of probabilities per move from training incalculable times + perfect memory of the current best results from play-outs.

Everyone:
