Well, I think it’s true and I’m not a mindless Union thug. Many good-paying jobs ARE being eliminated by automation and replaced by lower paying ones (if at all). It is a well documented trend. Also, don’t misunderstand: I am also not saying this is a bad thing, but it is inevitable.
I am in the software/IT field. While our area has certainly grown, tools that make us more productive (& enhance collaboration) will also, eventually, cost jobs. In the cyber security world, a lot of the monitoring that used to be done by people is now automated. I honestly think that 20 years from now, a lot of software will be automatically generated or functionality will be learned from observation or data. Again, not bad, just inevitable.
I am not smart enough to predict what the new jobs of the future will be...but there will be new jobs. Thirty years ago, I would have never predicted that companies would have entire IT departments, or that we would have entirely new markets like cell phones.
On the list of things I worry about, loss of jobs to machines is still pretty low.
