Totally see your point, granted. But it was the permanence of our knowledge and science and wisdom and arts throughout the ages that has - to some degree - given us progress. A collective memory.-

The further problem is that this impermanence is, structurally, a "default" for the current, dominating media - whereas it was only a fraction of knowledge that was lost or vanished when the imperative modes of transmission were "permanent-by-default".-

Further, methinks, we would be missing on a great opportunity - enabled by technology - to make knowledge permanent and accesible - going a bit beyond, from remedial action to constructive action ...

The other side of that goes to impermanence as a feature, the "right to be forgotten" and such aspects ...

... which are also important and in league with the "natural" entropy you rightly point out exists ...

... but the pressing problem is - methinks - on the other side of that spectrum, the side of guaranteeing what up to very recently had been a feature of information media: Its capacity to transcend time, and remain.-
