What if the most powerful technology in the world was dedicated to only one metric: your well-being? Two revolutionary trends are evolving at breakneck speed: our newfound ability to converse with AI on any topic, and the silent, constant recording of our digital lives. Currently, these technologies run on parallel tracks. In The AI Partner , Alon Halevy reveals the immense potential waiting to be unlocked when they finally combine. Halevy presents a visionary roadmap where these capabilities merge into a hyper-personalized companion focused not on selling you products, but on your well-being. At the heart of this vision is Oswell, a conceptual “operating system for well-being.” Imagine an AI that doesn't just track your sleep and record your purchases, but understands your past, protects your focus from digital noise, and helps you navigate your connections with others. But this future also raises tough questions. Halevy goes beyond the technical architecture to tackle the profound ethical dilemmas of this new reality. From privacy to the essence of human agency, The AI Partner asks what it means to live with an algorithm that knows you well enough to assist your every step. Ultimately, this is a manifesto for ensuring that as AI evolves, it becomes a trusted ally in a life well-lived.
