First, unemployment is a big problem. but producing robots and IT-related jobs will develp and I don’t think that can cause gap between the rich and poor. Also, as developing, related jobs will increase, so rather than studying and wanting jobs that can replace by robots, we can ready for threat of unemployment as studying robots.

Second, you insist about the problem of the leakage of personal information. I agree with that claim. But we should not ignore the increasing frequency of the robot industry and Internet information processing, which also increases the technological skills of information security.

I agree fully about environmental problem. It is assignment and duty for human.

The fact that robots don't have emotion is thought disadvantage, on the other side, it can be advantage. The jobs that need emotional sympathy and face with him or her cannot be replaced by robots. However, the jobs that need no emotion and rational judgement like judge or lawyer and be claimed maintenance of coolness in accident place like rescue workers is better to be replaced by robots.
