Even though I'm a bit guilty of it myself with my own space opera setting (it's supposed to have a retro aesthetic), it's surprising how science fiction has been so permeated by cynicism and what I can best define as "End of History" thinking that the only thing pop sci fi seems able to imagine is "the future will be the same as today (or even worse), but there will be Cool Laser Guns"
(lately even the lasers have been replaced by regular bullets)
What I mean is that much like it's harder to imagine the end of the world than the end of capitalism, it's easier to imagine our current capitalist system extending indefinitely but now In Space rather than imagine societal changes. Like, this it guys? We're gonna have to pay rent and fight pointless wars and be ruled by corporate suits forever? are we actually gonna have fucking CEOs as we explore the galaxy?
This is it? You can't imagine a better world than this?
Even when sci-fi authors talk about realism, it's usually about how to make ships pound each other harder with missiles, not how about society will evolve in the future, what changes might technology bring to society (the whole point of science fiction in my opinion). It's just Today, But With Lasers. We will still have corporations, nation-states, cops, war, the same society we have now. But Now With Lasers.
anyways, for a good start, read Banks and LeGuin, but there are others, lots more, who dare to imagine what actual futures might look like, they just aren't as well known
