Chiming in with my own find!

I've seen this person around a lot with crazy takes on AI. They have a couple quotes that might inflict psychic damage:

If I had the skill to pull it off, a Buddhist cultivation book would've thus been the single most rationalist xianxia in existence.

My acquaintance asks for rational-adjacent books suitable for 8-11 years old children that heavily feature training, self-improvement, etc. The acquaintance specifically asks that said hard work is not merely mentioned, but rather is actively shown in the story. The kid herself mostly wants stories "about magic" and with protagonists of about her age.

They had a long diatribe I don't have a copy of, but they were gloating about having masterful writing despite not reading any books besides non-fiction and HPMoR, their favorite book of all time.

There's also a whole subreddit from hell about this subgenre of fiction: https://www.reddit.com/r/rational/
