see, that’s MY advice to sci-fi and fantasy authors: if we already have a perfectly good word for something, don’t invent some goofy made-up term for it. relying on goofy made-up words to convey that your setting is Different Than The World We Live In Here and Now is lazy and annoying
in my fantasy novel cats exist but they’re called “purrlords”
books exist but they’re called “bound-paper flippityflops”
telephones exist, but they’re called “farspeakers”
guns exist but they’re called “killerizers”
