Around 10 years ago, in an obscure private close-knit investment chat group, a senior Apple engineer inadvertently blurted out how Apple has mostly solved iris gaze tracking and foveated rendering. When I pressed him why in the world Apple would be investing R&D dollars in this (I failed to make the logical leap to Apple mixed reality devices), he clamped up.

Apple plays the long game clearly. Wouldn’t be surprised if the Apple Vision Air already exists in an early beta form in their labs.
