>It's important to both suspend disbelief to enjoy fiction from reality and take fiction with a big grain of salt that it's often missing considerations of reality. Ironically, this happens in the utopian case with Star Trek, which gets invoked as an example of a valid and functioning "post scarcity" society based on fabrication and automation, despite the technology in that series being essentially magic.
The core of the Star Trek post-scarcity is a) near-free energy, and b) ubiquitous access to matter replicators. The replicator is kind of magic, but not total impossibility, and rough approximations are within realm of conceivable "future technology". But I think first and foremost, Star Trek is being brought as an example of post-scarcity so often because it's pretty much the only story that presented such society a…
I would say I'm more optimistic than you about post-scarcity. Bertrand Russell makes a case for the insanity of modern society by noting that during WWI half of British populace was sufficient to produce enough for all of Britain. Even if we allow for some margin of error in his statement, since that time productivity in the US has increased 4.5x since then.
To me the show is increasingly relevant. For example, it presents a clear answer to a popular criticism to UBI: what is to prevent everyone from staying home to play video games and leeching off society?
The optimistic answer is that once society can produce enough goods for everyone, the traditional value system of society (material wealth => proxy for contributions to society => virtue) loses meaning and will be overtaken by new ones (contributing to society => virtue).
I agree with most of your summary except the end. What if the problems in the US and around the developed world are more due to how society is organized rather than technological? I think the Star Trek value system is appealing and IMO something we ought to strive for.
