People connected to LessWrong and the Bay Area surveillance industry often cite David Chapman's "Geeks, Mops, and Sociopaths in Subculture Evolution" to understand why their subcultures keep getting taken over by jerks. Chapman is a Buddhist mystic who seems rationalist-curious. Some people use the term postrationalist.
Have you noticed that Chapman presents the founders of nerdy subcultures as innocent nerds being pushed around by the mean suits? But today we know that the founders of Longtermism and LessWrong all had ulterior motives: Scott Alexander and Nick Bostrom were into race pseudoscience, and Yudkowsky had his kinks (and was also into eugenics and Libertarianism). HPMOR teaches that intelligence is the measure of human worth, and the use of intelligence is to manipulate people. Mollie Gleiberman makes a strong argument that "bednet" effective altruism with short-term measurable goals was always meant as an outer doctrine to prepare people to hear the inner doctrine about how building God and expanding across the Universe would be the most effective altruism of all. And there were all the issues within LessWrong and Effective Altruism around substance use, abuse of underpaid employees, and bosses who felt entitled to hit on subordinates. A '60s rocker might have been cheated by his record label, but that does not get him off the hook for crashing a car while high on nose candy and deep inside a groupie.
I don't know whether Chapman was naive or creating a smokescreen. Had he ever met the thinkers he admired in person?
Chapman is a fucking moron, and not rationalist curious but deeply embedded in rationalism. “Post-rationalism”, when it was new, was nothing more than a way of being into (at the shallow end) Deeprak Chopra type shit for personal growth on “rational” grounds (“if it works it isn’t stupid” or whatever) without getting kicked out of the clubhouse. It’s harder to see those outlines now because mainline rationalists have effectively adopted that plus far more extreme attitudes in their day to day over the last 5+ years, so post-rationalism looks harder to understand and more interesting than it really is or was.
Chapman himself was trying to do rationalist existentialism (hence his title, “Meaningness”, the quality of being meaningful, with particular respect to “having meaning in one’s life”).
Of course he was naive, but he’s also just writing yet another completely oblivious ass-pulled blog pretending to do meaningful sociology with just whatever shit came off the top of his dome. It’s identical to everything else written in this regard within 15 miles of LessWrong and should therefore be ignored except insofar as its laughed out of the room.
