In his “Bleat” (which I did not read in its entirety) Lileks talks about pop cultural things that are recycled or “rebooted” over and over again and says we need some new things. I agree with that but I do not think steampunk is in that category.
According to Mitchell though (the first link) steampunk might be approaching the point of being “no longer cool because too many people like it.” That might be true and if so it’s perfectly okay with me. I have no interest in the kind of “cool” that requires extreme exclusivity. What good is coolness if it can’t be enjoyed by everyone?
