I think that is only because a reliable physical medium has not yet been
devised. Plastics materials are of doubtful longevity compared to gold
or ceramics.

In particular, the writable CDs do not have a fixing process to prevent
further exposure, unlike photographic plates (which are known to last
for 150 years).

On different continents.

I think the big weakness of digital has been that the quality of
conversion from analog was at first poor. Good current equipment
seems to satisfy the most critical sound engineers. (I'm not talking
about a $20 computer sound card here.)
