PHYSIX OBSERVATION

Meta has moved its social-graph advantage into an AI assistant, and Muse's record of interpersonal relationships goes far deeper than that of ordinary chatbots. Users gain convenience while handing over more detailed social data than ever before. Regulators and users alike should ask: can these profiles truly be deleted, or are they merely being kept somewhere else?
