From what I know, they are two distinct genres of fiction.
@fenchurchthesane: Sci-fi CAN be about things that could happen in real life. Jules Verne's sci-fi novels from the 1800s speculated on the idea of humans reaching the moon and in the 1960s we ended up getting there for real.
@Melriken: But if people from the medieval ages were somehow introduced to the technologies we take for granted today, they might legitimately believe it to be magic.
