No one has mentioned "syfy" yet. Saw it used to mean a sort of "sci-fi lite", with Independence Day as a major example. Think that was Ellison's criticism. Sci-Fi as a term has never bothered me. Is totally interchangeable with SF (ess eff). I am more bothered by the exclusivity of genres. Why can't a work be in both SF and an unrelated genre like romance or horror? An overly simple classification system always seems driven by people not wanting to have to think too much. Oh well, that sort of thing is everywhere in life. Like, the equating of wealth with at the very least the virtues of ability and competence. That kind of worship helps billionaires win elections.
