So if you read Harry Potter and the Methods of Rationality, and thought... …
"glowfic" apparently. written in a roleplay forum format.
This is not a story for kids, even less so than HPMOR. There is romance, there is sex, there are deliberately bad kink practices whose explicit purpose is to get people to actually hurt somebody else so that they'll end up damned to Hell, and also there's math.
I should have listened to the content warning because literally everything the main character (I shall call him Math Elk) says or thinks is completely insufferable rationalist buzzword babbling. Couldn't make it past two pages.
It wasn't an auspicious start when he gets on the plane and immediately treats a social interaction with a woman like a dang financial transaction.
OK kept reading, maybe the main character comes from the planet of weird insufferable nerds on purpose.
It got unbearable when Math Elk did nothing but spew nonsense at Carissa and she seemed weirdly OK with it despite not being a weird nerd. Couldn't maintain suspension of disbelief.
Wait math pets?? Tell me more. Are they cute? How can I get one? Will a math pet sit on my desk solving all my everyday algebra problems for me? How cute are they when trying to figure out excel formulas?
Update: I looked up math pet and it was not at all what I had envisioned.
