your essay was interesting. I have a difference among your opinions. Of course, robots can do the job much more efficiently. However, if humans can`t work, many people lose their jobs and don`t make money. Therefore, even if you make many of things simply by doing a lot of work, there will not be many people who can purchase it. Also, in your essay, you said that robots can make the environment better, but I think that more environmental pollution can occur in the process of creating and processing robots. So I oppose replacing humans with robots.
