Jon Evans is the only person I know who has read Yud's early mailing-list posts, and he was already an AI cultist and went on to work for Metaculus and Meta Superintelligence. There is probably interesting material in there but clearly Yud already thought highly of himself, already believed he was the Chosen One, already got defensive and wordy when someone criticized his ideas, and already posted voluminous pseudo-intellectual screeds which are not as consistent and logical as he believed.
Evans loves chatbot-summaries, but some science writers spent year at it and could not make the bot spit out useful abstracts. And he says he can skim a scientific paper in 5 minutes.
Selfishness sounds like it might be his way of thinking about some of this (I don't think he could allow himself to think "I am a fundraiser and pulp writer and married with no other achievements" but I think he knows he likes to be adored and control things).
When we get a proper history of this subculture, with names and dates and diagrams of the polycules and play parties and group homes, it is going to be wild.
