To look at the crowd here, you would certainly get that impression. We're mostly a bunch of old guys complaining about arthritis and diminished hand strength.
This is something I've been thinking about for a while, and I was finally moved to open the question for discussion by
@Westerly Wood mentioning on the current "strings" thread that he's thinking of moving to 11s because he's "getting old" and having problems with 12s. But the question is more than just being about us; what I mean to ask is, do we trend older here because young people are not picking up the acoustic guitar anymore? Or is it something else, like maybe we hang out here because we just have more time on our wrinkled old hands?
A lot of us are over the hill and soon to be under it. But check out folks like Molly Tuttle, Dom Flemons, Billy Strings, Samuel James, Hank III, Old Crow Medicine Show, Jason Isbell, Tyler Childers, singer/songwriters in general, and the whole world of newgrass.
Google around and you'll find plenty of great young artists. Here's a good article:

And take a look at who's buying Taylors. They have the youth market pegged: build 'em for recording and miking, not for hanging around on the porch or by the fire with friends. Gibson and Martin are also marketing and selling successfully to a lot of young players.
Keep in mind that younger folks don't like web forums as much as we do. Too slow. They prefer Instagram and Tik Tok. So my advice is, don't consider the LTG crowd a representative folk guitar demographic. In fact, if you look at all the folk guitars available now, you'll realize that this is lutherie's Golden Age. Someone's buying them.
But when all is said and done, who cares whether acoustic guitars are waxing or waning? I say let's just enjoy 'em and let the future take care of itself.
