Behind the Bastards just wrapped their four-part series on the Zizzians, which has been a fun trip. Nothing like seeing the live reactions of someone who hasn't been at least a little bit plugged into the whole space for years.
I haven't finished part 4, but so far I've deeply appreciated Robert's emphasis on how the Zizzian nonsense isn't that far outside the bounds of normal Rationalist nonsense, and the Rationalist movement itself has a long history as a kind of cult incubator, even if Yud himself hasn't fully leveraged his influence over a self-selecting high-control group.
Also the recurring reminders of the importance of touching grass and talking to people who haven't internet-poisoned themselves with the same things you have.
