I cannot agree to your opinion. You said that human jobs will gradually decrease if robots replace human work. But I think it is wrong. The 3D printer expert, the database manager, and the artificial intelligence expert, none of them existed in the past. Like this, more job will appear which is related robot. Next, I want to tell you that the probability  that robots create problem is less than people do. Finally, people can meet other people outside of work.  robots replace the human workplace, we can communicate with our neighbors.
