About

Plato 21 is a scenario about what artificial intelligence in the wrong hands means for self-government. The name is a claim: that the oldest recorded warning about democracy, a jury of five hundred tipped by professional persuaders, voting to kill the man who asked it questions, comes due again in the twenty-first century. We built it because the public conversation keeps sliding between two useless poles, breathless doom and bored dismissal.

We keyed it month by month. Fixing events to a calendar lets you check the mechanism and argue with the timing. A date is a claim you can be wrong about, which is what makes it worth making. The four parts are built from different materials, and the seam between fact and forecast is deliberately visible.

On the fictional actors. Parts II and III use invented names. Prometheus, Aegis, and Tianji are fictional AI labs; Veldova is a fictional mid-size European democracy. Most posts on the site, and the "Readers added context" notes on them, are fictional composites: accounts, handles, and metrics invented. Each carries one common misconception about democracy, with the correction beneath it. Posts with an "Archived · documented" badge are real, quoted, dated, and footnoted; anything without it is invented. The notes decay as Part II drifts and return in the epilogue. Where we name a real instrument, the EU AI Act, the Digital Services Act, the C2PA standard, we mean the real thing; where we name an actor, we do not.

What we want from you. Share it with someone who can act on it. Argue with it where these decisions are made. Steelman it before you dismiss it. If you find something wrong, tell us. A document people improve, not a prophecy people admire.
