Comment on M-DISC – DVD/Blu-ray compatible discs that may last up to 1000 yearsparent

Issue with storage is you need shelf stability without ongoing electrical/mechanical work refreshing data time to time.

For what? Nothing we do today will be even remotely important in 1,000 years. Any tiny fraction of a fraction that is important will have been copied thousands, millions, or billions of times into various formats.

  "I met a traveller from an antique land
  Who said: Two vast and trunkless legs of stone
  Stand in the desert. Near them, on the sand, 
  Half sunk, a shattered visage lies, whose frown,
  And wrinkled lip, and sneer of cold command,
  Tell that its sculptor well those passions read
  Which yet survive, stamped on these lifeless things,
  The hand that mocked them and the heart that fed:
  And on the pedestal these words appear:
  "My name is Ozymandias, king of kings:
  Look on my works, ye Mighty, and despair!"
  Nothing beside remains. Round the decay
  Of that colossal wreck, boundless and bare
  The lone and level sands stretch far away."
- Ozymandias - By Percy Bysshe Shelley
For what? Nothing we do today will be even remotely important in 1,000 years.

All sort of things done a thousand years ago still shape how we live today:

Who knows what the actions of a single, seemingly inconsequential, individual could trigger:

You know what every one of those things says in common? every generation between when it was created and now has decided it was important and made effort to preserve it. We have no clue or maybe only slight clues of what was lost because at some point some generation decided it wasn't worth preserving. Sometimes it was a hard decision for that generation when they realized they couldn't preserve everything, other times it was not cared about at all. Either way though, it was lost for all time because the chain of caring enough to preserve it was lost.

The data isn’t the valuable aspect of those examples. The metadata is!

We have a bunch of family photos that were preserved for a few generations. It sucks, many of them we know who they are, the most are lost to time and the death of memory.

Pictures without the context are just images of dead people. With the story, they are priceless memories.

Every single thing you cite has been, and will be, copied many times over and preserved that way. e.g. - We don't have the original Bible, we have eleventy-billion copies of it.

I don't disagree that a few things that happen today will be of consequence. I disagree that any single source of that data needs to last for a thousand years in isolation.

There are, I'm sure, one or two examples of thousand+ year old primary sources revealing otherwise lost information that was still relevant in some way. I suspect not many, other than as datum for academics to ponder.

Important information has always survived by copying.

https://en.wikipedia.org/wiki/Dead_Sea_Scrolls

Dating from the 3rd century BCE to the 1st century CE, the Dead Sea Scrolls include the oldest surviving manuscripts of entire books later included in the various Jewish and Christian biblical canons, including deuterocanonical manuscripts from late Second Temple Judaism, as well as extrabiblical books. As such, they cast new light on the emergence of Rabbinic Judaism and of Christianity, and their relationship with Jewish religious traditions.

One could similarly imagine a set of M-Discs from today that would be rediscovered 1000 years from now that could prove similarly useful to the people of the future thanks to data on them that has been preserved unaltered since today until then on that set of M-Discs.

Nothing we do today will be even remotely important in 1,000 years

The irony of quoting the work of a poet who died over 200 years ago is thick.
