As a fairly new member at Lesswrong, I've not until now taken to reading Eliezer's fanfiction Harry Potter and the Arts of Rationality, but the manga/amine Death Note gets taken up there, seemingly on par with any other form of media. It's the second time manga/anime's hinted at as a source of inspiration.

You COULD solve the FAI problem, but you need time to do other things too, and then the medium is of far less importance than the message. After all, if another medium can be more effective in delivering the same message - a film as opposed to a book, wouldn't READING be worse than anime since you could be spending that extra time working instead?
