Robots can do a lot of things, from housework to helping operate on patients. ⑴ Now they might be even smarter than you imagine. Alpha Go, an artificial intelligence (AI,人工智能)program beat top Go(围棋)player Lee Sedol from South Korea in four out of five matches. AI is that computers or computer software(软件)are able to have intelligent behavior, such as thinking or acting like a human. In our daily life, we already use AI in many ways, like Apple's Siri and search engines like Baidu and Google. ⑵People also invented wheel chairs(轮椅) that can be controlled by the rider's thoughts. And with the development of AI, it is possible that super intelligent AI programs like Jarvis in the movie Iron Man will be invented in the future.
