§ The Ledger
A durable historical record of AI.
An open-source ledger of AI history: events, threads, controversies, and the revisions that reinterpret them. Every claim is sourced and contestable.
Curator's note. This ledger treats AI as history in the making, not a running news cycle. Every entry is sourced, dated, and contestable; where the record changes, the history stays visible.
