The Bulletin's anchor pieces. A cornerstone essay is the publication's reference definition of a load-bearing claim — the kind of piece the rest of the catalog argues from rather than re-litigating. Cornerstone essays are revised in place when the underlying thesis sharpens; they are not retired. https://web4bulletin.com/topics/cornerstone-essay/ 2026-05-23T00:00:00.000Z https://web4bulletin.com/articles/three-metaphors-one-bet/ 2026-05-23T00:00:00.000Z 2026-05-23T00:00:00.000Z Idris Aksoy

A cornerstone essay. Web4 is the working name for the operating layer that replaces the app — agentic infrastructure, autonomous services, and the post-app internet — and the Bulletin's editorial position is that it is already partly built.
