Just in my lifetime I have watched my career vanish. I am a machinist and a tool and die maker, and just over the last 10 years of doing that job I have watched CNC (computer numerical control) drop the number of and required skill level needed from employees down to about 10%. We no longer need as many skilled tradesmen in manufacturing. Usually an engineer designs the part and a cad/cam program (computer aided drawing/computer aided machining) spits out the code needed for the cnc machine to make the part, then a minimum wage employee will load material into 3-5 machines that then spit out finished parts. No new jobs are created and entire departments are automated out. 6 minimum wage workers easily replace 60 workers (as these machines remove a lot of secondary processing as well as the manufacturing itself and are MUCH faster doing it) at the cost of half their collected yearly salaries. It's already here, we just don't talk about it.
