But eventually, you will run up against something never before experienced in human history--exhaustion of demand.
The problem with automation is that the robots don't want anything, and all they need is power and maintenance (that is much easier to perform than medical care).
They can supply goods and some services so much more efficiently than human labor that no human can effectively compete with them and still be able to eat. So the humans that formerly did their jobs have nothing to trade at market. They are forced to subsistence labor, if they are even allowed to do that. You can't afford the electric induction cooktop or the electricity produced by robots, so you have to burn scavenged wood in a hand-built rocket stove. The displaced laborer contributes no more demand to the robot-supplied marketplace.
Each worker you make obsolete removes their demand. The robots produce less, consuming only their most basic needs, and send most of the output to their owners. The owner class, who does not consume 100% the maximum output of their robots, slowly buys up all valuable resources with the excess, as those who wish to avoid subsistence lifestyles sell off their assets in order to stave off scavenging for roots, mushrooms, and squirrels. Perhaps some of them can manage a parallel economy trading in inferior goods and services, but the threat always looms that anyone too productive will be able to buy in to the robot-owner class and stop supplying the under-economy. Most everyone becomes Spam. They only trade with each other until they can be steak again. So everything in the under-economy sucks.
One laborer can maintain hundreds of robots, who can each support a specific want of millions of people, but only have thousands of owners. The owners don't want more than the robots can provide, so those humans that don't own can't manage to sell much of anything to the owners, except things that robots cannot provide [yet]: art, love, babies, etc.
Every unemployed-becomes-entrepreneur is a last-gasp effort to leap the widening gap between the haves and have-nots, like a salmon shooting past the open jaws of a grizzly. If you don't buy in soon, you might not have anything left worth trading for your golden ticket.
