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 88-89. The previous thread has passed 500 comments.
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, 15, 16, 17, 18.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Harry could disassemble the world and the stars into computronium - in fact star-lifting crossed his mind when he heard the first part of the prophecy. EY stated that there would be no AI analogy, and magical intelligence amplification seems more plausible anyway.
A different route to a mini-foom is that one can make luck potions. Then gamble, get money, recruit people who know how to make potions. Now you have huge amounts of luck potion, and provided your thought process is fairly random, you will always find the right answer (e.g. opening a random book at a random page happens to provide exactly the right insight). Routes to magical IA:
Luck potions.
A thinking hat - like the sorting hat, only it uses your brainpower to help you solve problems.
Efficient use of memory charms to spread insights rapidly through a group of researchers.
Use of telepathy to create a group mind.
Potion of thinking, made of e.g. ground-up crossword puzzles.
Potion of... OH CRUD.
Buy supercomputer time to solve problems in some physical form. Melt printouts into potion. Foom.
