Whither GenFic?

Is it a thing of the past?  A relic?  Something that used to be, like affordable public transport and factual facts and Treasures chocolate bars?  Every time I look for something to read in whatever fandom (cuz yeah, I have cleaned all my cupboards and drawers and tubs and showers and floors and etc, and also, I have had enough of reality for a while, thanks) and I'm hoping for a nice case file or just a story, the only choices seem to be slash vampire NASCAR AUs or, um, other differenter slash vampire NASCAR AUs, now with added superheroes, werewolves, and selkies. (And a playlist, cuz yeah, you need pop songs of questionable merit to read by, right?)

Is this a symptom?  If so, of what?
