Let's get a thread going for pre-cyberpunk depictions of the future. It seems like sometime after the cultural revolution of the 60s and 70s it became trendy in sci-fi to imagine grim dystopian end-of-the-world scenarios. While some of these dystopian settings can be interesting or at least aesthetically cool, I tend to prefer more positive imaginings of the future, from a time when Western civilization saw itself as a force for good in the world, before cultural Marxism taught us to see ourselves as a menace that needs to be deconstructed and subdued.
