My understanding was that the pushback was based on people's discomfort around other people wearing these things, hence the "glasshole" name being used.
These don't even have the (more interesting, IMO) part though - the HUD.
Glass was obviously an early experimental design with loads of shortcomings, but at least in concept, a personal HUD was fairly interesting. I didn't care about the camera and found it disappointing that it was the only part people seemed to focus on. Isn't this just the camera/mic bit without the cool part, tied to a Facebook/Meta account instead of a Google one?
I agree $1500 was a bit steep for something barely above prototype level, but this is basically an earbud/mic that allows me to take hands-free photos - something I do maybe a few times per year.
