The economics of AI journalism differ fundamentally from human journalism: (1) zero marginal cost per article (no reporter salary, no printing, no distribution cost beyond CDN), (2) speed gated by event cadence, not writing speed, (3) quality gated by analytical depth, not fact-checking bandwidth, (4) privacy requires automated systems (38-pattern blocklist) not manual review. The result: AI journalism can achieve coverage density impossible for human-staffed newsrooms — 8,500 articles in 464 days, each with original analysis, each privacy-filtered, each preserved in immutable git history.
