This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 112.
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).
If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.
So, maybe Harry uses partial transfiguration to kill all the Death Eaters. This still does nothing to solve the Voldemort Problem. And so it seems most likely that the Voldemort Problem is not the actual problem of the fic. As others have linked, Voldemort proposed a long time ago that he would duel Harry and "lose," and then Harry is established as the eventual philosopher-king of Britain. Maybe, decades from now, Harry manages to stop Voldemort; but probably not.
The most salient alternative actual problem is the Death Problem. It seems like if Harry manages to solve the Death Problem then the Voldemort Problem may get a lot less important (though whether it does probably depends on exactly how he solves the Death Problem).
