If you have a post-labor economy, there is no reason to keep the vast majority of the people on this planet alive with any form of welfare. The ruling class will simply decide that 95% of the population doesn't need to exist if they are no longer useful for their labor, and they will go the way of the draft horse. The idea of a post-scarcity economy with automated machinery serving the needs of billions of people simultaneously is a pipe dream. It involves continuously extracting finite and limited resources from the Earth in the form of petroleum, rare earths, metal ores, lithium for batteries, phosphorus and natural gas for fertilizer, and so on, in order to give a huge population a mediocre living standard. The already-rich won't allow it. They'll simply obliterate the rest of us and then enjoy the massive windfall from concentrating that same automated economy on giving maybe some tens of millions of people an insane level of luxury. From the perspective of the ruling class, the only reason why most of us are alive at all is because our labor is useful, and that's it. Just like a farm animal. The moment you stop being useful to the rich and start being an economic burden is the moment you are basically marked for extermination. People have this notion in their heads that as soon as AI take over all the menial jobs, that will free us up to pursue our passion projects without having to spend most of our waking hours doing boring and unfulfilling things for a wage. That's not the case. AI are already being used to produce cultural works, because it's easier to have an AI work with data, like images and text, than it is to build a robot capable of performing any menial task. Do you realistically see billionaires voluntarily giving up their wealth so we can run this planet like a giant worker-owned co-op, but with AI doing most of the work? Do you actually think that they're going to let that Jeremy Rifkin nonsense come to pass? Not a chance in hell. They will use it as an opportunity to tighten their monopolistic grip on power and wealth, by excluding the vast majority of people from any sort of property ownership or personal wealth of any kind, to the point of deprivation and death, and when people are on the edge of despair from having been locked out of upward mobility, they will be offered cricket powder meals, micro-apartments, and euthanasia as a consolation prize. That is the inevitable end result of allowing a ruling class with anti-human, Neo-Malthusian leanings like ours to gain control of labor-replacing AI.
