Read the article and select the best answer. Article: Who is smarter, human being or artificial intelligence(AI, )?The question swept the world a few months ago. In March 2016, AlphaGo, an AI program developed by Google, had the Go match with Lee Sedol, a South Korean Go player. He is the world top player of this old Chinese game. In October 2015, AlphaGo became the first computer program to beat a professional human Go player. And this time, it beat Lee Sedol 4-1. In fact, before the match, most people believed that Lee would certainly be the winner, because they didn't think that AI was good enough to beat the human mind. However, the result was disappointing. As a machine, AlphaGo would never get tired, while Lee Sedol was only a human and humans must have some weaknesses. AlphaGo's wins over a human champion show that computers can do more difficult tasks. Some people may worry whether computers are now smart enough to beat us at everything. But scientists say that is not the case. Real life problems can be more difficult than the Go game. Thomas Johnson, a scientist of AI said, "It's not hard to get a computer program to remember and produce facts. What is hard is getting computers to use knowledge in everyday situation. " We believe we can use the technology of AI to improve the world. Question: The match between AlphaGo and Lee Sedol is mentioned at the beginning of the article mainly to _ .
