I saw your opinion well. But there is a problem with your opinion. As you said, robots are cheaper and more productive than humans. However, if robots are used instead of humans, most workers will lose their jobs. Also,  even if the efficiency of robots' work increases, but it is companies that earn money, not labors. In the end, when robots are used instead of humans, the unemployed will increase and only companies will grow. We must seriously consider the gap between the rich and the poor.
