And didn't some futurists in the 20th Century predict that we'd live in a postindustrial leisure society by now, or at least have one in foreseeable reach?
For example, back in 1930, J.M. Keynes speculated on the "Economic Possibilities for our Grand Children
I draw the conclusion that, assuming no important wars and no important increase in population, the economic problem may be solved, or be at least within sight of solution, within a hundred years [from 1930]. This means that the economic problem is not-if we look into the future-the permanent problem of the human race.
And this would supposedly happen from ordinary capital formation and economic progress, without postulating anything science fictional given the knowledge base in 1930.
