The act of imagining the future has always been a quietly subversive activity. Portraying a different or changed society cannot help but be a deeply political exercise. By doing it, you’re implicitly passing comment on our present world and the way it will be altered by coming events or technologies. From HG Wells onwards, SF writers have imagined what will happen if we continue down our current path. If things go badly, we get a dystopia to warn us of the consequences of inaction; if things go well, we get a utopia to which we can aspire and work towards.
One of the core messages of the genre is that, “this too shall pass.” The world we know today – it’s political, economic and social systems – cannot endure forever. Change will come. Some people don’t want to hear that, but come it will. As SF writers, we get to model a vast array of possible futures. To remake the world according to our personal fears and desires.
The forces of conservatism seek stasis and security. They fear change, but SF writers revel in it. We dream of better worlds. We are literally paid to imagine that things are different to the way they are today, and that can be a hell of a subversive act.
