I have a feeling that both Jordan “Crémieux Receuil” Lasker and Curtis Yarvin will be present as guests. https://less.online/
Yud made them list him under both Project Lawful/Planecrash and the Sequences/HPMOR. I think he is really proud of his million words of forum posts about D&D, BDSM, and eugenics, like an elderly L. Ron Hubbard really wanted to write another bestseller.
They hope to get the creator of Worm (the webcomic serial fiction that Ziz Lasota was a fan of) and Dominic Cummings. Also some postrationalists like The Last Psychiatrist and Meaningness.
That is just life as a creator who makes meaningful amounts of money (you can’t control your fans or prevent them from misreading), but in addition, I think one purpose of these events is to corrupt people. Lobbyists host events in nice hotels with fancy catering for a reason.
