I think though that the dream is for it to get smaller and more human adapted until you get all the benefits, with normalized cues that make it more social, perhaps more social than the now-ubiqitious smartphone and headphones. But that is a long ways away.
The other thing that I think is not emphasized enough is that this headset is really a two way interface for personal AI, where it could be very compelling. Apple prefers to sell it as an entertainment/work device, but with all those sensors and upcoming multi mode AIs, it would be a whole new category. I think Apple realizes others have taken the "AI" flame, but they know it's important, so instead for now emphasize machine learning, but this will eventually become more like the interface for AI assisted imagineering and self guided entertainment.
