The problem with labelling something "proto-singularity economics" is that the whole point of a "singularity" is to hit a condition in which economic production completely outstrips not merely the demand for goods (overproduction) but even the ability to charge for goods (scarcity as experienced by people). We are still at the stage of a mere capitalist overproduction crisis and its ensuing capital glut.

It may well be true that we could convert our current economic condition into a post-scarcity economy by shifting away from capitalism, but at the moment we're stuck in an overproduction/overaccumulation/debt crisis.
