Honestly other than just extrapolating out what technologies will facilitate the rise of dystopias (while being weirdly obsessed with the aesthetics of dystopias to the point of it being dysfunctional to the objectives of the narrative and fiction) what have sci-fi writers actually meaningfully imagined about the future in the western canon?

For all the mountains and mountains of sci-fi books and tv shows written I am not sure there is actually much to show for it except endless descriptions of how colonization, war and authoritarian power will be facilitated by future technologies (in a way that superficially claims to be subversive but is really just technology porn politics be damned).
