well I think robots can be good in replacing human jobs when it comes to speed and robots don't need to rest and eat. The negative result of it is there is a high chance of people who are unemployed. Lots of people lost income if that happens.
Yes this would be the good and bad effect of replacing people with robots. It will help poverty to spread out even more. Many people are working at factories so many will be affected. Though the owner of the company will gain more production this have more income. Although it is a very bad idea.
