“Berkeley culture” as a proposed label for rationalist, effective altruist and AI circles

A user floats “Berkeley culture” as a name for the extended social world of rationalists, effective altruists, frontier AI labs and AI-adjacent circles. They argue that “Bay Area culture” doesn’t quite fit and that this world is not a direct continuation of traditional Silicon Valley culture. Instead, they trace its roots to Berkeley academics and social life, without suggesting everyone in it agrees.
