I think the main question will be if Meta can run the glasses under a different business model than ads/personalization. I know Meta feels like they missed out on owning the hardware ecosystem with mobile, but a big part of why Apple's product work is because their business model is not ads.

If they can fix their incentives there it will address 80% of the concerns in this thread.

Counterintuitively I think a passive screen affixed to your face will reduce your reliance on all other screens. Glasses aren't a great form factor for scrolling feeds, but they are much better at connecting you to your physical world (which phones are the worst at). That plus just the posture improvements [1] that glasses can provide over the phone may make this a winner.
