AI-written books and articles don't carry prominent disclosure labels the way ads now must in New York and the EU — and the implication is that creators avoid labeling them because consumers might assume lower quality. Search results confirm NY passed AI disclosure requirements for ads in May 2026 and the EU AI Act mandates transparency on some generative content, but there's no equivalent rule for books or articles, so publishers have no incentive to advertise AI authorship. The post correctly identifies a real gap in disclosure norms and asks a pointed question about why — though the 'we all know why' framing is more assumption than established fact. What's missing: the distinction between *legal requirement* (ads) and *voluntary stigma* (books) — the law doesn't require book disclosures yet, so absence of labels isn't necessarily intentional hiding.
