Metalenses

Smartphone form factor has been retired in favor of augmented reality lenses, available as glasses with your choice of frame, or contact lenses. Apple and Microsoft make the two main OSes as of 0BL, but the technology becomes public domain after The Liberation. Despite fitting within standard fashionable frames, smartglasses offer many thousands of times the processing power of todays fastest gaming computers. The contact lenses are driven wirelessly by an auxiliary computation unit integrated into a watch or piece of jewelry, and likewise offer thousands of times the processing power of today's most powerful systems. Regardless of the form factor, these devices allow photorealistic holograms to appear in the wearers view. They monitor gaze and brainwave activity for the primary interface, but also run the software for your personal virtual assistant. These virtual assistants are non-sentient, but capable of many advanced features, and speak in a convincingly human way. They can act on your behalf in many ways (making appointments, etc), as well as perform complex search and analysis tasks to answer conversational queries. They are powered by siphoning tiny amounts of heat from your body, but also have a battery capacity that allows them to last several days without touching you.
With the ratification of The Earth Constitution, all people are entitled to up-to-date Metalenses, as many of society's basic functions require their use.
