> I'd expect the bar to preserve any specific content to be a lot lower than what we had in the past. At the moment, I agree. However, as older civilizations rose and fell, their knowledge lived on in physical support, directly accessible by anyone who was taught how to read the language, therefore the assumption was that "as long as the language lives on, books are a good archiving support". When our modern digital civilization falls [1], I'm not sure most of it would be transmittable through long-term electronic archiving supports that may be easily readable (as easily as a written book at least) by future civilizations, because not only the language has to live on, but the technology needed to access the content also has to function. I also agree that some contents will always be more relevant to "backup". As for everything that happened on Facebook (same can be said for most social platforms), it is likely to entirely disappear with the company. One could even see it as a parallel civilization, that has no means of self-preservation other than that of their ruling entity's business interest.
