All of these indicate that such longevity is possible (see my main post).

Clearly, the reason that '13.8 Gy' is used here is that it's a well known time
interval and it puts the longevity of this technology into perspective in ways
that many will understand.

as a remarkable effort—not quibbling about trivia and silly incidentals.

Glass is the opposite of crystals. Crystals would presumably be longer-lived,
but their anisotropy makes them somewhat trickier to work with. Otherwise I
agree, and like you, I'm profoundly disappointed by the level of
"notacoward"'s comments in this thread so far.

You're right of course. I've assumed the stuff would necessarily be
crystalline (and would have to be to have such longevity). The word 'glass'
here being used for easier digestion by the public. (See my longer post for

Seems a bit of a waste to dedicate an entire 360TB disc to a single text
document like a bible, which is probably just a few KBs... /s

More seriously, they don't talk about reading capabilities (retrieval speed
etc). And what if it gets scratched? What is the error tolerance? At that
density, a single speck of dust could have dramatic implications...

I hope this reaches industrial viability, because we desperately need a
digital format that can approximate the lifespan of simple paper. At the
moment we are chained to a maintenance nightmare of periodic hops between
formats, with deadly consequences any time we miss a single jump.

Yeah, actual museum-grade archival is so much more than just having an aging-
resistant media. You also need to be able to read and decode it many years
into the future, which is really tricky to guarantee - you can't assume the
future generations will know how to make a reading device and remember your
formats/encodings. So it's a bit like _unzip.zip_ problem.
