How would you classify The Foundation? Classic sci-fi novel, right? But it has telepaths.. By modern standards, telepathy, empaths, telekinesis.. that's all magic. Fantasy. But in 20th century science fiction it was extremely common.
Especially given how some of the "science fiction" elements of it read 100+ years later.
On a more serious note, yeah scifi and fantasy can usually be distinguished, I get why it so often gets lumped in together as speculative fiction, even though it annoys me when I'm looking for one and have to sift through the other.
