Sure. But I thought it was assumed that we were talking about writing that would survive without any additional interaction for extended periods.

If nobody is there to refresh the digital data, tablets, and papyrus, two of these will last millennia, one won't even make two centuries.

We could store words on paper indefinitely if we keep copying it to fresh paper every so offen.

Obviously thats not practical or guaranteed for all of future history.

Most things last very long if stored properly. People tend to not do that, though. Probably why low-maintenance, high-permanence formats tend to keep the best.

you have not an eternity machine no
