There are media that would certainly last longer than our most cutting edge technologies, and the medium should fit the purpose. I think I said once that data intended to last forever (or at least several thousand years) should be imprinted on stone pyramids, along with instructions for building decoders and playback machines.
I would certainly love to see highly compact and efficient data storage that is relatively permanent. Perhaps someone will figure out a way to make holographic data cubes age-proof.

Perhaps what we need is a method of storing digital files on a shellac
disc?! They seem to last forever, barring disasters...
