Millions are downloading AI agents like Meta's Muse, which can order food, book travel, and call insurance companies—but only if you hand over your entire digital life. New York Times tech reporter Eli Tan spent weeks testing Muse and discovered both its remarkable capability to navigate complex tasks autonomously and the unsettling ease with which users outsource thinking to cute, fuzzy avatars designed to lower privacy concerns. AI agents represent a major leap beyond chatbots because they can autonomously access software, sign into accounts, and complete multi-step tasks like calling insurance companies without human intervention.
