I am just a new fish in this sea, but for me, the sci-fi has always been about how technological or social development, advancements or discoveries affect the further progress of manking, for example the Three body problem is an excellent example. Technology, aliens, social events (honestly, that is a bit new to me, I was surprised the Handmaid's tale is actually considered sci-fi and then I realized, yes, it is) and others are the main point of hardcore sci-fi to me. And then there is a Fantasy, which I have always seen as a battle between good and evil in any made up settings, doesn't matter if they are magical or futuristic, there can be medival sci-fi, where magic can be science and there is no battle between good or evil (Smoke, Ve službách klanu - not translated into English) or futuristic fantasy like Star Wars, which is clearly Fantasy. My question is, I have never really looked around in the wide world, I have no idea if this is official or only the rules of my own community I move in. And second question, if my works have a little bit of both, where it is a classic fight between good and evil but there is also hidden the deep philosophy (really, really well hidden) of sci-fi, what may happen to humanity in far away future, where do I put it?
