Sci Fi is a flavor of fantasy that favors grounded explainations over magic, yet can’t escape it entirely. In order for something to be sci fi, it must have something in it that can be percieved as “magical,” even in the “sufficiently advanced technology” sense of the word. Jump/warp tech, laser weapons, space warfare in general, most life support concepts, AGI… All magic as far as we know now. Any sci fi without the roots of fantasy is really just modern fiction.
Though at that point it stops being sci-fi and becomes space-themed fantasy.
