> [!tldr] They should follow the Apple Watch path, not the iPhone path. There's almost no reason to force a pair of AR glasses to be a *replacement* to a phone. They should function more like a new paradigm of input & output devices. Moreover, those inputs and outputs could be modular and composable to provide products of differing layers of capability. If you already have AirPods, you don't really need audio input/output. For example. | Use Case | Display | Camera | Speakers | Microphone | Head tracking | Eye tracking | | ------------------------------------- | ------- | ------ | -------- | ---------- | ------------- | ------------ | | Viewing calendar & notifications | ✅ | | | | | | | POV camera | | ✅ | | ✅ | | | | Replicating AirPods | | | ✅ | ✅ | | | | Overlaying visuals on the environment | ✅ | ✅ | | | ✅ | | | Overlaying controls | ✅ | | | | | ✅ | Each of these capabilities comes with its own requirements for power, technology, and manufacturing difficulty. A valid product could be built around any combination of them. **** # More ## Source - self
