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.
What kind of data is it? If it can be printed, you can just print it and store it somewhere safe, or print multiple copies and distribute it around. Plenty of 80 year old books are perfectly readable. That’d only be books printed in 1946 so nothing crazy. You can pay for professional printing so they can do it on good quality paper and so on.
