Indeed. And i expect preservation through dissemination will be the
best hope for much of this data to survive. But as you also mention,
bit-accuracy also comes (for now at least) with the Cliff effect:
potentially catastrophic data corruption of very large amounts of
data.

Uff... yes, OK, that is pretty dumb.
