Exactly. Economy of scale will cease to exists. Thus the demand for robots in the factories will stop making sense - what they would be making for whom? Nobody have money, nobody can buy anything.

So next step, business go bust, because there is just not enough billionaires to keep all of them alive. Another step is states go bust because there is no income to be taxed and there is no capital exchanging hands in buying goods which could be taxed.

If you mean bartering, then what people which has been pushed out by AI into uselessness are going to barter?

[skeledrew]

Not really. "Money" is actually just a middleman that facilitates bartering in new configurations, such as the exchange of goods/services with very different valuations. So there concept is retained.

I mean systems in which there're no expectations of giving something in return for getting something of economic value. That which happens naturally within family.
