Lee Se-dol, the 33-year-old South Korean who is the 18 time world champion of Go, finally beat Google's artificial intelligence program. It marks his first win in the ongoing challenge.

Since the AI already won three games in the five-game series, a series which is taking place in Seoul, the victory is already secured; however, the final matches are still being played out. It is hoped that these games will help the Google team get some valuable insights into how well the program functions.

And it seems that people like knowing that humanity can put up a good show in the face of artificial intelligence. Indeed, Lee's win was met with uncharacteristically enthusiastic applause. After the match, he remarked, "I've never been congratulated so much just because I won one game!"

DeepMind founder Demis Hassabis live Tweeted his analysis as the game progressed, and also didn't hold back in his congratulations to Lee.

You can watch the match in the video below, and continue scrolling to get a more indepth discussion of Google's AI program.


AlphaGo is an algorithm that has mastered the game of Go. To do this, DeepMind is using a type of AI called deep learning, which involves training artificial neural networks on data — such as photos — and then getting them to make inferences about new data based on patterns found in the information that it is fed. 

In this case, the AI predicts which moves to play next by researching expert Go players’ moves in games. It uses a process of trial and error, effectively getting smarter by playing itself.

Although AlphaGo was made to play Go, the DeepMind team wasn’t sure their program would be the winner. A few months ago, Hassabis, was quoted saying, “If we win the match in March, then that’s sort of the equivalent of beating Kasparov in chess. Lee Sedol is the greatest player of the past decade. I think that would mean AlphaGo would be better than any human at playing Go.”

Well Hassabis, It looks like that’s the case.
