If music is so valuable to us humans, then why can't humanity make a site like wikipedia for free music? There is a new generation growing up used to streaming services costing 10 bucks a month.
Wikipedia covers music very well. It often doesn't include the music itself, but there's a ton of great writing and history about music.
And many artists still publish CDs, vinyl records, and other physical artifacts just like they have for ~most of our collective lifetimes. If you want new generations to experience that kind of thing, then buy some of it for them to experience.
(Or, you know: If that seems like too much work or too much money, then a streaming subscription is only about 10 bucks a month. I spent a lot more than that on music when I was a kid.)
