So it's possible that, if we had a really huge, dense, wired city with excellent transportation, we would find a significant subculture of steampunk furries, or vampire gothic lolita hip-hop dance squads? Actually, this sounds like a lot like Tokyo.
And I expect that the next generation of hipsters will find a way to be irritatingly disdainful of a thousand cultures at once.
It's easy, really. Practice this phrase: "Man, what weirdos." You just have to selectively overlook the weirdness of your own subculture while recognizing and stigmatizing it in others. It's an elegant approach.
I would like to propose this as a thread for people to write in their predictions for the next year and the next decade, when practical with probabilities attached. I'll probably make some in the comments.
