Harry Potter and the methods of rationality is so tainted by the author, his agenda and the weird cult that is less wrong, I cannot recommend it (I have read it).
The story is honestly a vehicle to convey a world view while borrowing plot from Harry Potter and Enders Game.
It is fun in the beginning, but it reeks of ayn rand and juvenile oversimplification of the world. This all might be ok, but the story is written with an agenda and its like reading scientology fiction or something.
A rather successful AI researcher with a large fanfiction very weirdly tied into his craft, and his own discussion board/pseudo-cult who believe that unless his qualifications for “friendly AI” are followed the world will end?
And here I thought “My Immortal” was the weirdest Harry Potter fanfiction.
