Strategic Game Behind Screenless Design: Why OpenAI Hardware Chose 'Subtraction'

I noticed an interesting detail: while the entire AI hardware sector is frantically stuffing screens everywhere—the Rabbit R1 has a 2.88-inch touchscreen, the Humane AI Pin uses laser projection, and even Meta's smart glasses are chasing display interactions—OpenAI's first hardware device chose to cut all screens, returning to the primitive form of a "smart speaker." Is this a technical compromise, or a deliberately crafted differentiation strategy?
