Well I wouldn't say the claims go against known science, since catchamber is pretty clear that he's only speaking theoretical terms. Such as "consider if we had automated systems that took care of everyone's need without any human input." Like sure, if you assume away scarcity, we don't really have any scientific point of reference for how things would turn out, since that's so radically outside of the human experience up to this point. I don't find much use in such exercises though, as once you go outside of known parameters and create theoretical ones, you can make any logic work (i.e. if we start from the assumption that the Bible is the absolute truth of the universe because God, then yes, the universe is 6000 years old, and such like).
