Science fiction has always been the literature of the possible, the imagined. And just as we can imagine horrors worse then things are now, a monstrous AI intelligence torturing the last surviving humans, boots forever stamping on faces in a world defined by doublethink, we can also imagine what things might look like if the world was better.

That isn't panglossian optimism that things will all work out, anymore than dystopias are a prediction of certain doom. It's a vision of a better world that is, perhaps, possible, and exploration of how such a world might be achieved.
