    Doubt laser could etch deep enough to survive wear and tear for thousands of years.

      I mean, we have thousand years old paper and clay tablets.

      I’d be less worried about the depth of the laser than the depth of the corrosion that the metal might face over time.

      Glass or ceramic might work better.
