Dive into perspectives about how current AI features on smartphones and smartwatches are largely superficial "party tricks" and that the true potential lies in developing AI that functions as an "executive assistant." This advanced AI would move beyond simple tasks to offer proactive, context-aware assistance in daily life and work, such as managing schedules, preparing for meetings, assisting with project management, and even monitoring personal well-being.  This "indispensable" AI will be characterized by its ability to save time, solve real problems, and provide continuous optimization and learning, ultimately transforming how users interact with their devices. They highlight that the technology for this transformation already exists, and the next step is its meaningful integration into smart devices.
