I was always bothered when historians declare that "pederasty (homosexual pedophilia) was rampant in ancient greece, to the point where the typical greek man would have a wife for procreation and a young boy as a lover" or "in ancient egypt, their worship of half-animal deities resulted in the glorification and widespread practice of bestiality"... I can only assume that 10,000 years from now out culture would be judged by 4chan and others with similar results.
As far as "ancient storage media laster longer", what a glorious display of ignorance.... forget the benefits of modern storage for a second (size and speed)...
Very little data was EVER chiseled in stone, and that was erased by weathering. Most was either written on scrolls or painted on stone... the paint is long gone except for a few RARE locations where the environment was perfect for storage. Ancient scrolls also did not survive except for when in specific storage conditions (aka, in a pot, in a cave, in the desert, where it is very dry, unexposed to sun, no air flow, and constant temperature; these are not "or" but "ands", the pot is in the cave, the cave is in the desert, etc).
Current optical media could easily last longer in such conditions, and current bookbinding tech produces far superior books that last longer... that is, if made properly. The super cheap "paperback" books wouldn't last a decade... but quality books last a long time.
There is also the issue that the only thing that can really destroy our data, currently, is deliberate and consistent government action or a nuclear holocaust. Otherwise we will just keep on preserving our data digitally, migrating it from one format to another, from one media to another.
