Storage medium to last 80 years. (lemmy.nz)

I'm working on a project what requires around 1 to 2kb of data to be stored for ~80 years.

My thinking was a QR code (ECC H) etched into aluminium. Benefits being no bit rot & the assumption being cameras should still be commonplace in 80 years (And if QR isn't a commonly used format anymore, surely an AI agent could easily write an app for the user).

Does anyone have any better suggestions or think I've missed anything.

acid free archival paper. archival ink. Even non archival books can last quite awhile I personally own a book that is over 120 years old. Don't sleep on books.

    No, you'll fuck your back up.

    But, seriously, it is amazing. When I was a kid the school had an already very old computer that could run the BBC Domesday Project, a mid-1980s snapshot of life in the UK using the latest (for the time) multimedia technology, which included a bespoke LaserDisc player. By the time I used it, it was already failing and by the early naughts it was essentially lost media, with virtually no working hardware left and the Laserdiscs themselves starting to perish with age. Meanwhile, the original Domesday manuscript - written in the 1086 IIRC - still exists: coddled, protected and safe, but still there.
