Yes. People have been saying for years that “burger flippers” will be replaced by machines. And if they solve the problems with self-driving vehicles, then truck drivers will go away too.
Some people shrug and say, “Low level jobs! Who cares!”
But as you say, a huge number of jobs that were done from home during COVID can also go away. Many people with college degrees will be unemployable because they don’t have skills that are needed any more (the machines do the work better).
That’s transformative. It’s not Skynet, but it doesn’t have to be.
And tens of millions of newly unemployed people with no income stream just might get bored and cause trouble. That’s also transformative.
You can’t make money trying to sell things to people who have no jobs and no disposable income. If employers progressively cut their work forces to a bare minimum there will be a progressively smaller number of consumers capable of buying their products.
The entire way we think about work, compensation, and distinguishing / bettering oneself socioeconomically via ones efforts will have to be rethought.
So, it looks like the collapse of human society. Then, what’s the point of big business and government? Who’s going to pay for it? Yes, tens of millions of bored, disenfranchised people are going to be a problem. It’s back to wild west, frontier life, including Indians and banditos.
