M-DISC will apparently survive a thousand years — no light degradation, no bit rot, tested against heat, humidity, whatever else time throws at it. It’s a genuinely lovely piece of engineering, and it raises a question nobody in the marketing copy seems eager to touch: a thousand years of what, exactly?

Compare it to the millennium-old object actually in the news today for unrelated reasons. The Bayeux Tapestry is pushing 960 now, still legible, still contested, still teaching historians new things about a war fought in 1066. It survived by accident, on cloth, through fires and folds and at least one near-miss with revolutionaries who wanted it for wagon covers. And it’s dense with information: names, faces, a comet stitched in as an omen that we now know was Halley’s, though nobody embroidering it had any idea what they were looking at. It’s propaganda, but the good kind, the kind so well-made we’re still arguing nine centuries later about whose side it was really on.

Meanwhile the same week a new “permanent” storage format hits the market, I’m reading someone’s tired plea for people to stop running their LinkedIn posts through an LLM first, because the platform has quietly become an ocean of the same six paragraph shapes wearing different words. That’s roughly the daily throughput of the culture that just invented thousand-year media: writing optimized, on purpose, by the people producing it, to be forgotten by lunchtime.

I don’t read this as decline, more as a mismatch nobody planned. We solved storage well before we solved having something worth storing in it. The tapestry didn’t need permanent media. It needed a war worth stitching.
