This is a new thread to discuss Eliezer Yudkowskyās Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 114, and also, as a special case due to the exceptionally close posting times, chapter 115.
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 Authorās 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.)
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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 itās 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 āEliezer said X is trueā unless you use rot13.
With perfect sight toward the future, perhaps he could have. It's far from convincing that it would have actually helped, without blocking thirty other vulnerabilities.
Obliviation's particularly interesting because it requires no upkeep, but it's far from the only thing that would bypass Horcruxes. Voldemort's just as vulnerable to being repeatedly stunned, to petrification (hence the murder of the basilisk), to transfiguration, to the Imperius, to pretty much any mind-affecting charm. The biggest defense is, well, the same as anyone else's defense to the Killing Curse -- don't be there. Creating a defense specifically against large-scale Obliviation isn't very valuable if the attacker has countless further options to permanently disable anyone so defenseless as to be vulnerable to an Obliviate.
