We have clay tablets that are 3,000 years old and still readable. Those qr codes aren't etched deep in granite but some will survive through luck.

    Granite is astonishingly durable. A marble gravestone from as little as fifty years ago is already losing its edges, whereas I've seen granite stones from 100+ years ago that still look crisp and new.
