If these were AR glasses first, would we have accepted the cameras as a necessary evil? If that is the case, then the concern seems superficial.
AR requires cameras, doesn't it? It's the connecting to the internet, recording the video and not allowing people a single shred of privacy anywhere, eventually even in their own homes, that is galling, especially when FB is doing it so they can track you down and bomb you with advertisements.
If the AR glasses were very useful, then I would think so.
