I think I'd push back and say that nerd culture is no longer really a single thing. Back in the star trek days, the nerd "community" was small enough that star trek could be a defining quality shared by the majority. Now the nerd community has grown, and there are too many people to have defining parts of the culture that are loved by the majority.

Eg if the nerd community had $x$ people in the star trek days, now there are more than $x$ nerds who like anime and more than $x$ nerds who dislike it. And the total size is much bigger than both.
