I wonder sometimes if there's an earlier level of technology that society could basically "checkpoint" at and freeze, and then build off of. Capitalism today feels like it's hit the Red Queen Paradox - it goes around and around to keep the money flowing, but with very little actual progress. Indeed, most people seem to feel like the world is getting worse for all that work, and that many of the innovations of the last ~10-15 years are "fixing" things that weren't problems to begin with while creating new problems. And yet because all the substrate is shifting around, even if you don't break something someone else will. Could we go back to a world of redundant interchangeable parts where if somebody breaks something, you just cut them off and use a substitute that works just as well?
Or maybe that's well and truly gone and we're just fated to another dark age. I'm reminded of the Smarter Scrubber documentary that found that basically the whole supply chain was gone and it was impossible to make something useful in America.
