Structural Findings from 150 Years of Tech Dominance
1. Physical vs Digital Moats Unlike pure software waves (1990s-2000s) with near-zero marginal cost, Generative AI requires unprecedented physical infrastructure expenditure, matching the capital intensity of Gilded Age railways and Standard Oil refineries.
2. Infrastructure Bottlenecks Historical magnates achieved monopolistic power when controlling non-replicable choke points (Rockefeller pipelines, Bell telegraph lines, Ford assembly lines, modern GPU clusters & proprietary web data).
3. Regulatory Inflection Points Antitrust intervention historically lags technological waves by 20 to 40 years. Standard Oil operated for 30+ years before the 1911 breakup; AT&T maintained official monopoly status for 70 years under the Kingsbury Commitment.
