I guess I didn't look at it that way. Or maybe I chose my words poorly. <<; Seems the problem stems from classification a lot of the time too, since they're blended so much. Thor, for example. Alien yes, and it's admitted that they have super advanced technology. But at the same time it's considered magic by many (I apologize for my lack of comic book knowledge). Is it really? Is it somehow both? "Any sufficiently advanced technology is indistinguishable from magic" as the saying goes.
What I'm more driving it regarding my variation comment is that one seems to be more varied than the other, because SciFi suffers from a slough of genre technicalities in the eyes of the people. Like Batman. Just..normal Batman, no extended Universe. SciFi or just Fi? Does something like Superman really seem SciFi-y enough to most?
Though I wouldn't really count a modern day setting with a dictator as Science Fiction; just Fiction.
Though I still think Fantasy is more accessible to the common person. Holm was right in that SciFi generally requires one to think more, something that's been shrinking in popularity for the vast majority of my life. Or so it has seemed. Magic works because magic. Superpowered mutagens, OP'd fictional elements, and spaceships? Not so much.
Of course it could just be the cultural zeitgeist of this cycle.
Forgive my tendency to speak as though I'm still in my own head. < _<;
