I think robots’ substitution of human labor is quite reasonable, as they tend to be more effective in terms of doing housework. And the best thing is they will never get bored nor tired, which is something people can’t manage to achieve. But, besides the pros, we have to anticipate the cons as well. If we heavily relied on robots, we would not get the chance to exercise at all, sadly in the end, human beings would get more lazy and weak.
