I think that while science and engineering jobs will be activated and other jobs will fall behind accordingly, job diversity will be maintained. Humans can focus more on their artistry and leisure because simple labor jobs disappear and new jobs are created that require creativity. I think the acceptance of robots will create new jobs that only humans can do.

I don't think it's desirable to oppose accepting robots due to older people who haven't adapted to them. By the time robots are commercialized, the young are leading the world. I think the duty of the young is to help the elderly adapt, not to rule out new things.
