getting Physical media
While a digital photo can be whisked to the other side of the planet in an instant, a printed photo can be displayed on a wall or held in a wallet.
A pdf can be read on screen, but a book with an inscription can be passed from a long dead great great grandparent to a newborn.
Which would you rather your child have. A video (file?) of you talking to her, or a bundle of letters?
Physical has two meanings. And those meaning are intertwined.
There is also the simple matter of getting your data off the devices. I know lots of people who use their phone cameras, but few ho can do anything with those bits in there.
Remember the BBC Domesday Project from 1986. I think it was the 900 year anniversary of the Domesday Book, so the BBC created a new version for the digital age.
Unfortunately by 2002 they realised that there was hardly anything left which could read the laserdiscs that the project was stored on. So the BBC worked on a project to make a web version. The irony was that the original velum bound book was indeed still readable over 1000 years later.
Sometimes the simplest, physical solution beats the latest digital one.
