How AI Ate the World by Chris Stokel-Walker explores the history of artificial intelligence and then turns to a documented account of the harms it has already caused, to workers, to creators, and to the information economy, before pivoting to address speculative concerns about an extinction event. This review reads the book in light of its evidentiary method: namely, that it is composed of named, on-record interviews, which lend it a documentary quality that more distanced academic entries would not have. The method is not applied consistently. Western sources are interviewed directly, while Kenyan, Ugandan, and Indian data labourers' situations are reported through other journalists' articles, rather than the author's own. In doing so, Stokel-Walker uses the book to pivot public discourse around specific, documented harms in a direction away from speculation of AI extinction risk and toward the immediately actionable.
