Who says anything about enforced sloth? A lot of art and science happens because people need to put less work into staying alive. We don’t HAVE to become slothful with extra time on our hands. We could become a society of the bored and boring marking time until death. Or we could become a society of creators and artists finding new frontiers to push. The choice is ours.
Who pays the otherwise bored individuals to pursue some scientific question (another area where big-data, analytical computer programs and their small number of programmers are taking over), or create some art, and why? The glorious “we do”, so that’s by taxes, and where does our income for those taxes come from? Everyone is on the dole?
