As much as I like books and bookstores, @Hawaii_Jake, they’re going away, and there’s almost nothing that can stop that from happening for bookstore survival “as just a bookstore”. I believe that there’s a business model (probably yet to be developed) that will enable some to survive in a marginal way just run by and for book lovers without hope of great financial return. But I don’t envision many people growing up with a dream to be a book seller or owner of a bookstore.
But just like clipper ships died out (to name an industry that I would have grieved as you do bookstores), and a lot of art, culture and history went with them, and whaling ships, too, there still are some square-rigged ships sailing all of the world’s oceans. But they’re not commercial ventures. And there is no more Flying Cloud.* They exist as training ships for merchant marines and navies around the world, extremely specialized research ships where the presence of metals and motors would degrade the research, historical curiosities and adventures for youth, etc.
Maybe “public libraries” should morph into “book rental” shops, for example. (The book lover and reader in me has always celebrated “free public libraries”, but the libertarian conservative contrarian knows that “there’s no such thing as ‘free’”, that libraries are mostly another government expenditure and bureaucracy that keeps a lot of technology stuck 100 years behind the times, and that “private enterprise could do it better – whatever it is – and it would probably be cheaper and more convenient, too”.)
In fact, I think that libraries, being perceived by users as “free”, have probably indirectly contributed to the demise of independent bookstores, or prevented even a notion of a market for “book rentals”, which could have flourished. (But would still be threatened in this digital age.)
I think no matter what happens with “publishing” in the next 50 years, “books printed on paper” will become more and more rare and exotic except to collectors and bibliophiles more interested in the art form than the content.
* However, there is a Maltese Falcon. A clipper ship of a sort does still exist. I can still dream.
