The leading edge of this wasn't mass unemployment, but wage pressure on unskilled jobs that, about 50 years ago, made it almost impossible for people working low skill jobs to support a family and spouses had to go to work. The next wave will be that the jobs themselves cease to exist because even low wage workers are far more expensive than machines in *tons* of scenarios.
A few points...
- When I was a kid back in the early 60s, my dad worked and my mom stayed home. Our family had one car and lived in a 900 sq ft house. No luxuries, the house wasn't even air conditioned. If a family today was willing to live that same lifestyle they'd find it possible on a single wage earner's income. But they're
not - they insist on houses twice the size of the one I had as a kid, they insist on two cars, the latest electronics, etc., etc., and they go in hock up to their eyeballs.
This is a choice that they're free to make.
- There's little excuse for workers to be "unskilled" these days as there are many programs available and many employers provide training.
- There will continue to be many non-automated jobs.
- Yes, many jobs may cease to exist. There will be new ones. So what? It's been that way for a long long time.
- As baby boomers like me continue retiring, the workforce will shrink. Automation is a solution, not a problem.
What are the 3-5 million people displaced in those two examples going to do for a living instead?
If you can speculate about automation that doesn't yet (and may never) exist, I can speculate that there will be new technologies, industries, and jobs available that are unknown today.
Your question is akin to someone in the early 1900s asking "If automobiles take over transportation, what will become of all the people who care for horses, build wagons and tack, raise feed, clean stables, and so forth? What are they going to do for a living instead?" Y'know what? They found new jobs in new industries and the world improved as did their own lives.
The sky isn't even close to falling.
