User Mag's investigation into AI-generated content flooding Substack reveals a platform facing the same quality-dilution crisis that plagued Medium—except Substack's direct-payment model means readers are paying subscription fees for algorithmically-generated writing they mistook for human curation. Creators can use GPT-4 to churn out daily posts at near-zero cost, making the platform's open-access distribution system an arbitrage play for AI-spam rather than a differentiated publishing platform. Without credible markers of human authorship or enforced quality standards, Substack risks commoditizing itself into the same space as its competitors.
