I think the one weakness of text is context. In 2,000 years, if someone finds an inscription reading "Thanks Obama", what will they make of it? They'll might know that Obama was a president of a country. Without context it would be hard to tell if this was 1) genuine sentiment 2) snarky criticism or 3) ironic. Good luck with "Covefe" or whatever. My point is that context matters a lot, and (I assume) that it can only be reconstructed through a lot of text.
