I think we could only grasp a post-scarcity concept at this point in history due to global communication and exchange of information.
For anyone wondering: what in the hell are they talking about? resources on earth have true limits...
I'll try to clarify: material resources are truly scarce, but resourcefulness is not (think workarounds/equivalents via design). Without money as an obstacle or barrier to access of information, we could possibly see the next version of a creative renaissance, if you will...'weapons of mass creation' and solutions to longtime problems. Not a utopia, just way better than our current model.
