When a robot is capable of doing a job that 20 people can do at once and also more effectively and efficiently, it is going to affect the job sector very well more than you think.It is not a big deal to program a robot. I do not think that we would need 10 people to program a robot. One person is enough to do this job. So, just because a robot needs to be programmed, it does not mean that robots would not affect the employment rate in a negative way.
