People talk about whether or not it can be afforded and then point out the dollar coat of living, taxes and so on. Money is not a real thing, its a construct. Its so complicated that nobody here is going to be able to prove we couldnt afford ubi. But rhat doesnt even matter since money is only a framework we use for our markets and economies. Instead of fussing with money figures, which will never do anything besides confuse people, we can look at concrete things instead. The physical and chemical reality of this world. It is undeniable that because of automation, a complete restructuring of our society will be needed. The only limits in such a reorganization are those of the physical world, not those of our current paradigm. So, how much energy is there to go around? How much food and how many materials? What is the maximum amount of any of those things that we might collectively have? What are the limits of physics for how much energy we can harvest from the sun? That is where the conversation needs to begin. And i think we will all find that even with todays technology there is plenty of everythong to go around.
