I doubt society will go fully paperless, there are times when you need a thing that can be crushed, folded, whatever and doesn't run out of battery, so unless e-ink technology develops in a very specific way I don't think every eventually will be replaced, and even without purely functional applications I think art would never ever go fully paperless for many data security (leaking art before it's complete), economic (things are more expensive when they're limited in supply, and making either legal or illegal copies of digital things is so much easier) and sentimental reasons (it's just nicer to have something physical) reasons
