You don’t need to tell me that people deliberately choose dead trees; I am one of them: I collect books and have more than most collectors. Same goes for vinyl.
The writing is on the wall, however. In 100 years it won’t be a thing, just as fountain pens and wax seals aren’t today.
Yes, they will still exist, and yes, people into whatever type of historical reenactment that is will still have them, but there will be no industry around them like there is now.
I mean, of all the things you mentioned, it's by far the most likely to still be usable in the future. Even in a post-apocalyptic world people might figure out how to play vinyl. MP3s? Not a chance.
Full disclosure: I never liked cassettes. Oh, and I made the mistake of choosing Beta over VHS....
And yet, the longevity of a humble cassette tape far exceeds that of the average website. Websites ("digital products" if we must) change, they delete old/offtopic articles for SEO reasons, they change designs to fit in more ads, their owner ship changes hands, the image links break...the list is endless.
There are Gizmodo articles from < 10yrs filled with blank blocks with an "image not found" message in them. At least the cassette's changes are due to physical degradation only.
