If I’m understanding this correctly, you’re looking for fiction that focuses on framing more of cultural and societal shifts than technological changes?
What you’re looking for is difficult to find in the framing of Science Fiction because its very framing invokes technological advancement - technology is the application of science, and machinery is the result of technological innovation. Science fiction is, at its core, about how discoveries in science may change the world.
Nonetheless, you may want to look into the sub-genre referred to as “social science fiction”. Although it’s not going to be devoid of advanced technology, the focus will be more on the social and societal impacts thereof, than the machinery itself.
I have, thank you! Unfortunately, I don’t see the niches I’m looking for, and even when they do, they’re basically dead. I can only scream into the void so long…
