Your essay was interesting. Among your opinions, there was an opinion that if robots replace humans, jobs will be reduced and unemployment will rise. I disagree with this opinion. First of all, it is human work to make robots. That's why I think there will be more jobs about robots, and the unemployment rate will not decrease. And I disagree with you that there is an environmental problem in your opinion. We can use materials that do not cause environmental pollution such as electricity or renewable energy in robots. Then I don't think environmental pollution will happen.
