Comment by Diogenesian

Not "the rest of history," but relative to the ~1800-2000 period of steadily increasing literacy and educational attainment.

The European Dark Ages after the fall of Western Rome was a real thing. Many people regressed to the Stone Age for hundreds of years, and we lost almost every written work from ancient Greece and Rome. That can absolutely happen with the US and EU by 2200, especially considering digital information is far more fragile over centuries than papyrus and parchment.
