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?)
I don't think that it would be necessary to literally transfigure an AGI. Since it's possible to cast spells which react in a certain way to a trigger/specific change in surroundings, there's likely potential for creating artifices on the complexity level of scripts/programs using spells.
I think it would take quite a while to advance this science to the point where it could create an AGI (perhaps sped along depending on how easily it was integrated with Muggle computer science), but I think that if HJPEV thought about creating powerful optimization processes using magic which actually did what he intended, a huge power boost would result. Especially because AFAIK, the wizarding world has no parallel to programming, so only Muggleborns would really have a hope of understanding what he was doing.
