This was an april fools joke.
This is a new thread to discuss Eliezer Yudkowsky’s my chapter of Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing the fake April Fools chapter, which is now published. I suggest refraining from reading comments here until you read chapter 82. After you've read chapter 82, I suggest all discussion of this chapter to be kept here, with links to comments in the previous thread.
Is the idea that he would break the story by transfiguring an FAI? (Is that possible?)
What pedanterrific says. There’s lots of artifacts that display computing abilities (the Sorting Hat being the foremost example) which suggest that you don’t need to explicitly transfigure computing hardware (which is suggested not to work around magic anyway), you can probably just specify the software requirements and they get implemented somehow.
