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.

2kb, by what coding, but just good quality paper? would require few pages. Possibly protect it by good cover, box, vacuum air off.

We have over 2000yo scrolls, so 80y should be ez with good materials.

Note, that most modern materials are intended to last few years only, get good quality paper and ink, if printing, use bigger font.
