This is not the first time in human history that “technology” eliminated jobs and it will not be the last.
I am in my 70s and I can think of dozen of jobs that no longer exist because of technology. Going back in history the list would almost endless. The final results (almost) remains the same, but the manpower need to create those results have gone down, which in turn made the final product both cheaper and more readily available.
My only advise for young people just starting out is to look for a career that would be difficult to automate (such as a trade, electrician, carpenter, mechanic and so on).
You’re right, mostly.
The trouble here is the scale.
This is most definitely the first time this has happened at such a scale.
I think the scale is what most do not understand or are afraid to admit.
