Well, an digital book is the same concept as a paper bound book and is arguably more conceptually similar than a tablet. You can't easily encrypt and hide a paper book or distribute to multiple backup points. Paper books are much easier to censor and burn. A Kindle is an e-reader, one of many devices that can be used to read e-books. If your e-reader is destroyed, you can buy another one and restore your digital books from backups. Nobody can revoke your access to an e-book without DRM and it is very easy to strip DRM and backup your e-books. Nobody but me can change the copies of e-books I have stored in various mediums. Clearly the paper book and the digital book have different trade offs (I love paper books) but books are not the most durable medium in history and paper books are not categorically more durable than digital books. I would bet good money that in the far future, if humans exists, the vast majority of books we have today will have survived directly because they were digitally encoded and stored at some point in their history.
