Google's artificial intelligence program AlphaGo continued its victorious march on Thursday by crushing the world's go champion Lee Se-dol of Korea in the second round of their historic five-game match.
Its victory gave additional weight to claims that AI has prevailed over humans in the extremely complex board game that requires creative and strategic thinking.
It now looks increasingly uncertain if go grandmaster Lee Se-dol will be able to defend his pride and honor.
The second match started with Lee as white and AlphaGo as black.
Although, Lee admitted his mistakes during yesterday's press conference the result at Four Seasons Hotel, Seoul, did not change today.
Lee seemed much calmer than yesterday; it was AlphaGo that made the unconventional move that surprised commentators and Lee. He took much longer before putting down his stones, using much more time than the day before.
However, this led to Lee's downfall because AlphaGo's use of time was far superior to Lee's. Throughout the game AlphaGo led Lee by an average of 25 minutes.
After Lee's failure to revenge his defeat, he now has only three rounds to defeat AlphaGo.
Koreans have started to call AlphaGo "Al sabum," which translates to Master Al.
