Many years ago, when scientists tried to make a robot to do some human work, they could never thought about how far the robot could go. Today, some scientists even predict that the wisdom of robot will surpass human being and take place of us. In the science fiction movies, the directors have explored the consciousness of intelligent machines, who showed how these machines controlled people at last. The directors warned people that they may lose the dominant position in the future. Recently, a robot was given the citizenship and it became the first robot to be treated as human being. The public was shocked, but when they saw the robot could communicate with human beings and question about matters, they felt scared. Maybe in the future, the robot will replace us in many aspects.
