I think the worst aspect of using robots is that humans become lazy. Because as the saying goes, a lazy brain is the devil's factory. When people have less work to do they usually think about others more get angry and become aggressive. Conflicts arise from here. Perhaps the use of robots will make the world's few people rich and the majority of people poor.
This means that your way of thinking is still weak when you say that about the use of robots in most jobs. Because robots were also created by humans who were not born naturally into this world, humans still have work to do in designing robots and carrying out further research into the creation of robots. This means that we as humans still have to think about creating anything that can be used to complete every job more intelligently, because everyone definitely has limitations in working hard so they still need to think about working smarter by not relying too much on their energy every day.
Now try to think about when you are old enough but still have to work quite hard to earn money, even though some other people have worked smartly without relying on more energy to earn money. Apart from that, I also don't think that the use of robots will make a few people rich and most people poor, because those who can open a robot repair shop and are able to repair damaged robots will still have jobs and income through these services. And now there is one question for you, will the presence of tractor machines that can be used to plow fields make animals like buffalo starve because buffalo power is no longer used by farmers?
Very serious question. But the tractor has revolutionized agriculture. And for this the buffalo will not starve nor the farmer will starve. But in this case, when the land was cultivated by buffaloes or cows, not all the land was under cultivation because there would be lack of time to cultivate with cows.
Suppose you own a hotel or think of a hotel near your home. How many people are working there? And there is a lack of people for his work?
If there is no shortage of workers, who will benefit, and who will be harmed if robots are used to replace workers? Of course, the hotel owner will benefit and the workers will likely suffer. Again suppose 1 robot is given as a replacement for every 20 people. Then 20 workers lost their jobs. But how many people does it take to fix a robot?
(I certainly respect your development theory and thinking and I'm not against technological development, but I think that if the use of robots is not regulated, the chances of jobless workers will increase.)
