It is true that in some cases there are short term negatives for a small group of people within a specific trade. In exchange there are large benefits to society as a whole. Large enough to outweigh even the small groups inconvenience. I.E. I would rather be a permanently unemployed dock worker today, than a gainfully employed dock worker in 1900. There is certainly an argument to be made regarding the pace of change, and retraining/educational opportunities. But the automation driven job-pocalypse just isn't going to happen.
