Kids fantasize about being adults, or at least they fantasize about having the freedom and power that adults seem to have. That’s why so much of media made for children features kids doing adult things: solving mysteries, fighting monsters, having adventures, thwarting adults. Oftentimes kids have the clarity and imagination to see the supernatural for what it is, while their parents are too stuffy and boring to see what’s in front of their eyes. In these stories, kids get to be the heroes by playing the part of adults.
I have a confession: I haven’t actually read a lot of classic science fiction, and most of what I have read, I hated. Clarke’s too horny, Bradbury’s too racist, Dick’s too pessimistic, Orwell’s too reactionary. But one book in the “canon” actually stuck with me to this day because of its exploration of non-human intelligence: Asimov’s I, Robot.
