Seems like many in this thread are thinking about conservation. Thats positive.
Not all paper (papyrus, wood or stone) based documents remains till this day. Effort was made to conserve it because, through different times, enough people thought that knownledge was worth being remembered.
If a interactive paper is meaningful to enough people, it will be preserved.
You could say the same of oral traditions, which were also preserved: but that doesn't mean that oral traditions are just as good (in terms of information transfer) as written ones. Keeping up a digital paper would be much like an oral tradition, with each new generation having to re-implement it for current devices.
