EDIT: books last longer (decades or centuries) than SSDs. But M-DISCs can allegedly last for millennia.
That said, there are clear advantages to books. You can't page through an ebook nearly as well as a physical reference book. That's admittedly somewhat balanced by the existence of search. Physical books can also pay much more attention to the aesthetics of print and layout. Eink readers and epub/mobi/az3 formats are atrocious for this, whereas iPads with PDFs are somewhat better. There's still works that can't be captured in those formats though, like pop-up books, raised/embossed/textured printing (which I've seen used in poetry), or illuminated works. And books don't need power.
Books don't change. The online written word is subject to revision and change, as are ebooks. A physical volume which one owns and holds cannot be memory-holed.
There's studies on mammal populations, and as their preferred number of group sizes increases, the 'differentiable' traits also increased. So mammals that preferred to live in large groups had more visible differences in phenotypes than small groups.
If social systems are just an extension of phenotypes to some degree, then all that's really happening is people wanting to differentiate and they have a small differentiable desire in any given direction.
but you be you.
On the other hand I have a ton of physical books on my shelf, and can specifically look at one, remember what it’s about, and where I read it. The book itself is a kind of memory totem, and over time I’ve built up a nice little physical collection of what I’ve “emptied into my mind”, to quote Franklin.
I don’t have the same thing for the ebooks I’ve read, and it gives me a weird feeling of amnesia.
I find that this helps remember books that I read years ago, and usually the single quote is enough to jolt a series of memories about the book.
That said, I also own physical books and they are in glass bookshelves around my office and living room. I do like the looks of them and they can be a conversation starter as well when friends come over.
