That is a bold statement. Meusums are filled with non-gold artifacts!

yeah this seems to be ignore the massive amount or pottery and ceramics we have.

Pretty sure stone wins by volume.

Encode your data in pyramids! Presence of a pyramid = 1, absence = 0. Hope the data format still makes sense in 8000 years!

Interestingly but perhaps not surprisingly, Moore's Law extrapolated backwards in time would be vastly more expensive than this.

We might get 10^14 more bits out of something that costs 10^-7 as much today, but that's only 21 orders of magnitude out of a suggested 1200 or so.

The universe only has 10^50 tons of mass, so it's meaningless to even attempt to describe what would that cost would look like.

I'm personally saving up to buy a bit of storage when it only costs a thousand universes or so.

Moore's Law says nothing about "bits stored" or "cost" of storage, and it makes no sense to extrapolate it before the invention of integrated circuits.

It's actually quite interesting to extrapolate our current exponential trends before ICs as a thought experiment. Kurzweil semi famously uses it to push his arguments: https://www.kurzweilai.net/ask-ray-the-future-of-moores-law

I do know what Moore's Law literally says. I thought it was fairly obvious I was generalizing, but yes the text as written is incorrect.

If you're not into the thought experiment, that's totally fine.

Encode your data in a QR code made of pyramids. Future generations can find out what it says once they reinvent smartphones and travel to LEO.

And then: “never gonna give you up, never gonna let you down…”

There's like so many kinds of pyramids we can definitely encode more bits with sphinx's and stuff.

> gold is the least reactive metal

Platinum I believe beats it. But it is rare to find in antiquity because of the high melting point.
