Hard to see how Google or Facebook keeps their advertising models in that environment. There aren't enough construction workers and data scientists to buy everything.
which yes, will completely destroy the consumer economy and social structures and current forms of governance
That is hardly will be of any consolation. AI will probably destroy capitalism, but not because it will replace some useless f.ucks from their useless computer jobs (most of them will perfectly fine find another more useful job, if only way less paid), but because with surveillance and totalitarian control that AI capable of, socialists like Stalin or Hitler will build resilient and durable society where no member will have any way for resisting.
There will be, when two third of the office workers will be replaced by AI.
It is astounding why so many people does not understand how consumer economy works. I think it is more a matter of the copium, because, well, it is generally hard to accept the truth that in five years you will have to haul bricks as a job, and the guy who used to put that bricks on one another and make three times less than you in your tech job now will be your new boss.
And advertising models in that environment? Why should something changed for it?
Who re these people?
