AlphaGo won its first game on Tuesday and followed it up with another victory on Thursday. The hattrick victory for AlphaGo sets a new milestone for Artificial Intelligence.

Artificial Intelligence is definitely some years away from becoming mainstream and AlphaGo’s win sets a precedent on how AI can be put to good use.

However, not everyone is in favour of AI’s dominance. Renowned cosmo physicist Stephen Hawking has been advocating against AI and has said that AI can potentially affect humans negatively.

“Honoured to be in company of Lee Sedol,” said Google co-founder Sergey Brin. He added,” The potential of AlphaGo to beat world champion human player could be used for world’s benefits.”

I am bit stunned and speechless with this victory of AlphaGo over Lee Sedol. Lee Sedol put out a great fight in the third game forcing AlphaGo to reason its moves. Proud of AlphaGo team and Deepmind AI  can further help scientists solve various world problems,” said Demis Hassabis, Founder and CEO, Deepmind.


Lee Sedol sounded apologetic for his third-straight loss to AlphaGo. He said,”I misjudged the abilities of AlphaGo and apologise to people who trusted me. I showed better gameplay today but AlphaGo was quick to improvise on its moves.”

In the five game series, Lee Sedol has lost it 3-0 already and the world champion player urged everyone to show interest and continue support for the fourth and fifth match.

AlphaGo stood strong today with its fighting tactics but it took significantly longer to make its moves – even the most basic ones.


Many top Go professionals commented that AlphaGo displayed unorthodox, questionable moves that initially befuddled humans but made sense in hindsight.
