I've heard it before, back when "zines" were our obsession (pre-Web) -- we were going to make "slick" magazines irrelevant by becoming shallow, narrow, stupid and childish only very popular. For some reason, anything that a lot of people like and control is the end of the world as we know it.
I believe it was Spider Robinson who said "95% of Science Fiction is crap. 95% of EVERYTHING is crap." And I will be willing to bet that no matter what turn the world takes, there will be people left behind who think the new world stinks.
And by the way, the world as I know it has ended about five times since I was old enough to notice. And so what?
Ted Sturgeon. And his number was 90%.
