The problem is that all the jobs you list require at minimum above average intelligence. 50% of the population has below average intelligence. There is right now little economic demand for anything they’re capable of producing, and that little is declining.
In future, there just will be no jobs for most such people.
OTOH, in a robot and technology driven economy, there is likely to be a great deal of stuff produced with very little human input, which is of course the definition of productivity. Extend the productivity curve indefinitely and at some point humans become basically redundant to the economy.
So what do we do with all the people for whom there is not and cannot be an economic role in society?
It is quite possible, IMO, that in its final act of creative destruction the market will destroy itself.
I’ve always suspected that these shiny futuristic plans include getting rid of about five billion lesser people through some engineered virus. This won’t happen until the elites are sure they can live well without via technology. This will also allow them to “save” their precious earth from the hungry masses.
Just a wacky midnight fever dream theory ;)
Yes, if the robot revolution happens as expected, that will be the problem. It will not be just another era of capitalism vs. socialism or communism, but an era where a large portion of the population will have little or no way of earning an income.
And no one need dwell in the fantasy that all the unemployed will somehow "create their own job". They won't. A few will, but the overwhelming majority won't.
This conversation has come up before and I think this mass elimination of jobs would lead to the biggest redistributionist government anyone has ever imagined.
