Right now people have to point their phone cameras at at the thing they're photographing or recording, it's a very clear visual signal to others and there are cultural norms for this behavior. If a person is doing this in a common tourist destination that's more acceptable than pointing your camera at somebody else's children without asking them first. Imagine how uncomfortable it would be for somebody to hold their phone at eye level and point it at you the entire time they're having a conversation with you, even if they say they're not recording or anything like that. Having a distaste for smart glasses is pretty consistent with the status quo.

I mean, that really isn't true. There have been wearable and carryable hidden cameras for ages and we also have 360 cameras that no longer need to be pointed at what they are capturing.
This isn't changing anything about what is available to purchase, and if anything, these are relatively more obvious.
The actual change would be, that if these become widely adopted, those types of cameras would be everywhere.
You're right, it's possible and common to be recorded without somebody pointing a phone camera at you. That doesn't negate my point, right now the norm is that in many situations you _can_ record to your personal device without informed consent but you shouldn't. That will change if these types of cameras are everywhere.
