I wonder if you can Obliviate physical decay and return the brain to the state that it was in immediately after (or better, before) death. It seems unlikely, but then so is thinking with the brain of a cat, so who knows? If Obliviate works by altering brain states, and Magic recognizes a dead brain (so long as not too far decayed) as still a brain with all of its prior states from when it was alive, then it just might work. Obliviate 2.0 if necessary.
Remembering isn't the same as decaying. Forgetting isn't the same as regenerating.
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 116.
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.)
