There is one major point you have to consider about sci fi. The rise and golden era of sci fi were during times of great nationalism. This was in large part the US (who I will focus on, but a similar picture is true across the world) had real and present enemies to unify the people against. The "golden age of sci fi" is considered to be 1938-1946. WW2 was 1939-1945. Star Trek of course came much later, yet Gene Roddenberry was born in 1921 and flew nearly 100 combat missions in WW2. To say he this period had an influence on his views and life would be quite the understatement! During these times of nationalism, people looked outward for enemies and inward for unification and progress. You can see this exact metaphor within the federation. The enemies take unfamiliar shapes and forms from other literally alien cultures. Cyberpunk started to emerge during the 60s and 70s, with Neuromancer being released in 1984. We went from World War 2 to Vietnam, the rise of anti-nationalism, and an American people ever more able to find their own enemies from within. We went from a government that culminated in sending a man on the moon to a government that, especially after the end of the WW3 that did not happen - the Cold War, seemed to lack any direction or purpose eventually culminating in a behavior mimicking society of simply finding its own enemies within and eating itself alive. And that trend continues to this very day. The reason sci fi had a utopic future vision was because that's what seemed probable. Today how do you perceive the future in a couple of hundred years? I think "The Expanse* does a phenomenal take of considering this without resorting to trope. I also think Deep Space Nine was also well ahead of its time here. The episode "Past Tense" in particular is something that seems practically prophetic of the times today, down to the exact area and timeline.
