"Hacker culture" is a myth - not in the sense that it's false, but in the sense that it's a set of stories that people like because of their storytelling power, and its exact historical truth is not particularly relevant. As a myth, it tends towards better remembering things that make better stories, like great men inventing things through sheer force of will. And as a myth, it's a story about our origins, which were no doubt messier than we would like to remember. That our present does not seem as awesome as the myth is an unavoidable effect of myths.
But there a few historically true things that are relevant here: first, that an important part of "hacker culture" unequivocally originated in the Bay Area (Fairchild Semiconductor, Homebrew Computer Club, BSD, etc.), and second, that "consensus" has been an important idea in this culture for a while - an obvious example being the IETF's "rough consensus and running code".
