Is there ever going to be a post-scarcity era, or is scarcity contextual? Perhaps it is just going to be a moving target, like AI seems to be? Once a chess playing program that could beat the world champion was a pipe dream. The same goes for Go playing programs. Once a pen was a specialized instrument that had to be handcrafted for certain professionals. Now, they are practically free. Once, getting water involved significant personal effort for almost everyone. Now almost everyone one in the industrialized world thinks of it as something practically free.

One of the things which might throw a monkey wrench into the futurist/sci-fi idea of a post scarcity society is the Pareto Principle combined with the perception of relative poverty. Across all of history, productivity has been unevenly distributed. Even people who are wealthy on global/historical scales will feel poor if confronted with wealthier neighbors. Psychologists have concluded that the feelings of relative poverty are very real, and it's this relative poverty which is most strongly correlated with criminality, not absolute poverty.
