This could turn out to be true, or somewhat true, in some number of years (perhaps more than 10).
No matter the specifics of what happens with AI, I do think that a big percentage of humans will have nothing to contribute to the national economy. They will be expected to sit at home. Perhaps they will be given access to abundant goods in a time of plenty. But they will have nothing to do.
The devil makes work for idle hands, and if AI does all the work while people just sit at home, I think there will be a lot of trouble: people get bored easily.
In those giant apartment complexes they're building everywhere.
“I do think that a big percentage of humans will have nothing to contribute to the national economy.”
Well, even today there over 100 million adults in the US that don’t work... but seem to live pretty good.
I think that number is going to grow pretty fast. The societal upheaval will be unmatched, the economy as we know will no longer exist. Morality (the rules for living) as we know them today will, for the most part, be upended.
There won’t be a lot of people. With AI and robots you don’t need a large labor force. The useless eaters will be slaughtered in the billions by drones and robotic cheetahs whose mounted rifles never miss.
Just because it’s horrifying doesn’t mean it’s not coming.
