Tim Ferriss shares his own book sales data showing a roughly 80% collapse in print copies sold between 2022 and 2026 — a drop that tracks almost perfectly with LLM adoption. He argues prescriptive nonfiction is the canary in the coal mine for AI disruption of information-based businesses, and that the only durable moats left are voice, taste, and transformation — not information transfer.
I recently asked library staff at my local library if they have seen lending similarly go down, and they indicated they have not yet seen a noticeable difference, which might indicate that libraries are not yet being impacted. Maybe because of the lack of cost associated with lending compared to purchasing books.
