You're assuming that a culture as ossified as modern wizarding society has lots of people striving to create new spells en masse, and that it's sufficiently easy to do so that they'd be getting created if the people were trying and "slots" were available. That's absurd. Also, you seem to have no understanding whatsoever of the Interdict of Merlin - it says that spells above a certain power level can only be passed between intelligent minds, with no intermediaries(like books) allowed. The best I can assume is that you're engaged in circular reasoning, with the lack of new spells proving the slot theory proving your weird interpretation of the Interdict proving the lack of new spells.
The next discussion thread is here.
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 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now 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.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
