The article proposes 'Guardian Angels' (GAs) – highly personalized LLMs designed to emulate a user's values and preferences, enhancing productivity and cybersecurity. As powerful LLMs become ubiquitous, a coherent strategy for harnessing them and ensuring personal security is lacking.

GAs aim to solve the principal-agent problem by unifying the user (principal) and the LLM (agent). Users would focus on defining goals, with GAs acting as personalized digital twins, managing tasks and security, such as screening messages for advanced attacks. This approach offers increased productivity through higher-quality emulation of user outputs and trustworthiness due to shared values.

Achieving GAs requires techniques like online learning, active learning, and a local, log-oriented UI/UX. The author suggests a startup model for development, initially targeting power users and knowledge workers. The current chatbot model, driven by misaligned incentives and a race to replace rather than augment users, is deemed insufficient for future needs.
