I think the main issue with Google Glass was the creepiness factor of the camera. I feel for mainstream adoption, these devices shouldn’t include a camera, at least initially.
However, I personally haven’t heard much negative reaction to the Ray-Ban Meta smart glasses. Perhaps because they are so inconspicuous, people don’t realize they have cameras in them?
Google Glass is from the early 2010s 2013/2014 ish. People have gotten (for better or worse) way more used to having cameras everywhere in public
