Smartphones are incredibly powerful and underutilized. What if your phone—or eventually something even smaller, like a watch—was the only computer you carried, and every environment you walked into provided the right peripherals? Screens, keyboards, cameras, speakers—all dumb surfaces that light up when your compute device is in range. CarPlay already proves this powerful idea: your phone becomes the brain[^1] of your car, and the car’s screen, speakers, and mic are just the I/O. The phone does the computing; the car provides the interface. Apple is already partway there. Continuity Camera turns an iPhone into a Mac webcam. But it’s clunky—you have to prop up the phone, aim it, dedicate the whole device. Now imagine standalone wireless cameras, purpose-built as continuity peripherals. No screen, no storage, no OS to maintain. Just a sensor that joins the local network and becomes available. Same for displays (like CarPlay), keyboards, any input surface. The logical end state: the ~~phone~~ *personal computer* itself doesn’t need a screen (or much of one). It shrinks to a puck in your pocket or a band on your wrist. It becomes truly personal, always with you, and the interface adapts to wherever you are. Walk into your office and your desk display activates. Sit in your car and CarPlay takes over. Step into a conference room and the room’s camera and screen become yours. Or simply converse with your computing device through your wireless ear buds on the go—no screen needed. No cables required. The platform already supports wireless collaboration between devices. It just needs to be pushed further. [^1]: Yes, I know it’s not the actual computer running the car’s System
