I think young people and records is grossly exaggerated; I only know my son's friends who are college educated, and none of them own or think about records; they're mostly into "streaming".
Unless you're a "geezer", or "geezeress" who already owned a bazillion records when CD's came out, this analog thing doesn't make a lot of sense. As an example, the OP on one thread is crying the blues because he can not audition very expensive cartridges; I think he's considering cartridges in the neighborhood of 4K. Now unless you're exceptionally well heeled, that's a lot of dough.
As "audiophiles", we rationalize spending amounts that are out of proportion to our income, but this analog thing is even outside of that; rationalize or not, I had to see what the fuss was about, (especially since I owned so many records) and now that I've gotten there, I won't be climbing this ladder unless I can climb a money tree in my backyard.
I think young people and records is grossly exaggerated; that's because records don't make a lot of sense for young people, and the young people I've come into contact with are college educated and money savy.
In regard to the increase in sales, Geezers returning to vinyl would account for that, and those increases are compared to almost no vinyl sales, which makes them seem even larger.
After all of that, I'm going to spend the day enjoying my records; that's what geezers do; BTW, I'm discovering many new records that have hardly been played; although they're copies or replacement records, that's still a nice surprise.
Happy spinning.
