AI is when computers or computer software are able to have intelligent behavior，such as thinking or acting like a human，In our daily lives，we already use AI in many ways，like Apple's Siri and search engines Baidu and Google．

Some People may worry whether computers are now smart enough to beat us at everything．But experts say that the case．Real life problems can be more difficult than the Go game．For example，humans can watch a person throw down a cup of coffee and know that the result will be a mess on the floor．A computer program would have to know the size of the cup，the height of the cup from floor and many other things to find out the result．But we never know what will happen in the future．
