I might be wrong but I think paper seems more durable through all the destruction that could happen. Paper books probably fare better in solar flares, power disasters or if internet becomes more heavily regulated and expensive in some places. Some types of paper do really well under water.

This isn't just about books of course, if some content is only streamed from one source then it's definitely got less chance of surviving than lots of copies of files or physical copies. I better like the chances of all the books scattered around the world.
