“My own feeling is that science fiction, of all the different forms of literature, is the one that most easily accepts the notion of change. Things are changing very quickly, and any kid who thinks about it knows that the world in which he or she will be a grown-up — which he or she will be helping to run — will be considerably different from this one. Maybe better, maybe worse, but different. Science fiction explores the future world.”
This is one big part of what I love about sci fi.
