If you've not read this, strap yourself in - you're in for a ride. Eliezer, an AI researcher, has created this novel from a simple yet fascinating standpoint - what if Harry was a brilliant rationalist who engaged the magical world from a scientific standpoint? Don't dismiss this because it's a fanfic or incomplete - it introduces rationality, breaks many fantasy and geek tropes, and builds off Rowling's universe in a highly entertaining and thought-provoking page turner (I guess a modernization of this idiom would be "iPad flicker").
