TvTropes says that the Yudkowsky-insert protagonist of Project Lawful/Planecrash! is driven by desire to have 144 children (and prove his society wrong for not paying him to have 144) which sounds like Scott Aaaronson? Did they know each other in those days?
I am glad that all I knew about Yud in 2022 was "wrote a Harry Potter fanfic that I did not finish, and runs a website where people pretend to be experts."
Just this week Scott Alexander wrote a long 'joke' about how the fe-males just want to attach themselves to a high-status man like (guess who) Curtis Yarvin (bonus self-own: the joke implies that Curtis Yarvin is not inviting the narrator to parties any more) https://archive.is/akSnc
Yud has distanced himself from some of the things he posted before LessWrong, but he keeps citing the Pathfinder fic on twitter (here in 2022) (here in 2025)
