If you want a book on the rationalists that's not a smear dictated by a person who is banned from their Wikipedia page for massive npov violations, I hear Chivers' The AI Does Not Hate You and Rationalist's Guide to the Galaxy are good.
(Disclaimer: Chivers kinda likes us, so if you like one book you'll probably dislike the other.)
