I think most of simple jobs would be changed by AI. For example, not only drivers working for transit, but also blue color workers, I mean all the simple jobs can be done by AI, to move something and do a arrangement. even their calulating skill is better than human. but it takes a lot of time. because so many people are working now and some people afraid of AI's ability. they wouldn't allow it so they would make new laws to prevent robots come to their job. but now AI takes our job little by little. so we have to prepare for the future that would happen to us
