Should we use robot in our lives?

Hello! Everyone! I went to a student-led discussion. The topic was should we use robot in our lives. At the begining of the discussion, I agreed that we should use robot in our lives. Just like my friend said during the discussion robot could do some simple and repeatable work for human, so it saved a lot of time and human resource. Also, the robot could do some dangerous work such as high-altitude operation, mining and diving。If they can deal with the problem that is dangerous to human, why don't we use them? In my opinion, using robot is a good idea for human. However, I also agreed with some students that people can not depend on the robot. Once people rely on the robot too much, human may not control the robot especially when the robot has intelligence. It will be a big challenge for human. When the discussion almost finished, a student's words changed my mind. She said people should consider to use the robot carefully. Because if some people intended to use the robot to commit crime such as murder, it would be difficult for human to find the clue of the real criminal. Even if we found the criminal, they still had the excuse for which they could say there was a system error. This makes me rethink the topic question. While someting benefits us, it may bring some risks.
