Behind the Google brain: is AI a kind of technology, or strategy?

On March 2016, AlphaGo, a computer program developed by Google DeepMind, played the board game Go against Lee Sedol, the most famous Korean Go player. It beat Lee in a five-game match with a final score of 4 games to 1. The success of AlphaGo has shocked the whole world. Meanwhile, the development of artificial intelligence technology (also known as AI) has come back on table again. Based on deep learning, AlphaGo has conquered the obstacle of board game, so the next step, as people concern, does that mean AI is heading to a level of manufactural industry that machines can take over human's life? Google proved that their concerns would come true.
