Unlike what common people believe, EMP won't damage magnetic storage media, and definitely won't touch optical media. Flash memory is vulnerable.
You might have to replace microprocessors in all the connected devices though if the fuses don't work correctly.
That seems less likely than, say, a house fire or a conventional bomb
Yet a citywide EMP seems far more likely than the next Great Chicago Fire.
I had this discussion recently. Here’s the hat trick of digital over paper: an ebook can be unpacked and printed on paper! All of the contents are human readable - it’s mostly HTML and CSS - and can be re-encoded into an ebook with no loss of fidelity. It can also be easily read (see aforementioned HTML and CSS) without any difficulties, even in its encoded format on paper.
All books in existence can be stored on my harddrive, while they won't fit into my bag.
