The largest differentiator to other devices by Apple really is the always-on cameras and the idea that you can/should use the device with always-on cameras in public. Otherwise Meta/Oculus have already done just as much as Apple has done here. Apple’s entry into the market just heats up the discussion around the “Metaverse” again.

I work in the space myself and wearing a VIO system on your head can really give you a lot of health and personality information. The device sees your iris and can identify you. It can analyze your gait and with some “AI magic” even notice and detect movements of your extremities outside the visual field of its cameras.

Devices like these can also be helpful in the medical space though: Not just for diagnosing diseases in the brain or of the eyes, but also help with therapy of patients by augmenting reality with virtual content that can help. One classic one is Parkinson’s patients who can walk again normally with some virtual visual guides on the floor.

Clearly that’s not the main goal of Apple, and obviously not of Meta, but it’s not all bad if used correctly. A privacy first approach is definitely necessary. And it’s not completely true that M$ doesn’t give a damn. With their Hololens they did for instance introduce a privacy preserving mapping and localization system. Nevertheless Apple has a good privacy track record compared to other tech companies.
