>What if all the authors of culturally/historically significant works throughout history had thought like that?
Nothing much would have change, since it wasnt up to them whether their works surviced, it was up to their "fans".
In fact, if they had thought like that it would have helped, since they would have assisted this process (trying themselves to get their works preserved).
Besides, 99% of the internet is not culturally or historically significant except in the broadest sense (in which everything is, as an artifact of its era, etc..).
