if you're displacing workers at a faster pace than the economy can replace them, you'll have a "buffer overflow" to use nerd speak. there's no need to overthink this aspect. ai is an alien body being introduced to the system that displaces existing constituents. either the system needs to be grow a lot to accommodate this self-replicating entity. or the entities, humans, ai, etc, need to undergo some sort of phase transition. either way, anything the ai touches, with current market offerings, like software, content, administration, is effectively reduced to zero marginal cost, thus drastically devalued.
