Artificial intelligence: Google’s AlphaGo beats Go master Lee Se-dol
A computer program has beaten a master Go player 3-0 in a best-of-five competition, in what is seen as a landmark moment for artificial intelligence (人工智能).
Google‟s AlphaGo program was playing against Lee Se-dol in Seoul, in South Korea.
Mr Lee had been confident he would win before the competition started.
“AlphaGo played consistently (稳定地) from beginning to the end while Lee, as he is only human, showed some mental weakness,” one of Lee’s coaches, Kwon Kap-Yong, told the AFP news agency.
Mr Lee is considered as a successful Go player, having won many competitions in his career.
Go is a game of two players who take turns putting black or white stones on a 19-by-19 grid (棋格). Players win by surrounding their competitors pieces with their own.
In the first game of the series (系列赛), AlphaGo won by a very small chance – Mr Lee had led for most of the match, but AlphaGo managed to build up a strong lead in its closing stages.
After losing the second match to DeepMind, Lee Se-dol said he was “speechless” adding that the AlphaGo machine played a “nearly perfect game”.
Experts said that Lee Se-dol had brought his “top game” but that AlphaGo had won “in great style”.
The AlphaGo system was developed by British computer company DeepMind which was bought by Google in 2014. It has built up its special skills by studying older games and teasing out so many kinds of ways of play. And, according to DeepMind CEO Demis Hassabis, it has also spent a lot of time just playing the game.
“It played itself, millions and millions of times and each time got a little better – it learns from its mistakes,” he told the BBC before the matches started.
This good circle of continuous improvement meant the super computer went into the five-match series stronger than when it beat the European player late last year.
Does this mean artificial intelligence is now smarter than us and will kill us humans? Certainly not. AlphaGo doesn‟t care if it wins or loses. Does it mean that artificial intelligence will soon take your job? Possibly you should be more worried about that.

When I began to move to Auckland to study the law, my mother was a little worried about the uncertainty of living in a place that was so different from India, where we lived. She worried about the shortage of jobs and the cultural differences that I would face.
I came to New Zealand in July 2013. I found the people were very nice and supportive. Soon after I arrived, I realized the importance of getting a part time job to make a living.
Deciding to do this on my own, I spent a whole day going from door to door for a job. However, I received a little or no reply. This became my daily activity after college for a few weeks.
One afternoon, I walked into a building to ask if there were any job chances. The people there were very surprised, and advised me not to continue my job search in that way. As I was about to leave, a secretary in the building came up to me and encouraged me to stay confident. He then offered to take me to the Royal Oak area to search for a job.
Along the way, I realized I had run out of copies of my resume (简历). The man stopped at his friend’s office to make me 15 extra copies. He also gave me tips on dressing and speaking. I handed out my resume and went home. The following day, I received a call from a store in Royal Oak offering me a job.
It seemed that the world always gives back to you when you need it. And this time, it was a complete stranger who turned out to be a real blessing (祝福).
