For me, the spy nature of the glasses is quite different than the regular security cams.
That's because you're seeing a single possible use case and ignoring all others. They can also be:
- an assistive device for people with difficulty remembering people's names
- an assistive device that reads things to you through earbuds
- a real-time restaurant menu translator
- a heads-up display that provides information from your phone without getting it out
- a real-time navigation assistant
- a quick way to take a picture of things that you want to look up more information about later
- the world's fastest business card scanner
and so on. Some of these things require cameras; some don't.
In addition, sometimes things go on in those places that people would like some "social privacy". Sometimes people have affairs, sometimes just dating, sometimes just a business dinner, sometimes people discuss business, sometimes the owner says no - it is their property.
Well, yeah. And that's their right, at least up to a point where it becomes an ADA issue, and then it isn't. But either way, I think you're vastly overstating the concern. Unless I'm there to specifically catch a person who is having an affair, me having a photo or video of that person having an affair is not going to affect that person's life in any way unless it somehow gets posted on social media and they are close enough to my friend graph to get auto-tagged.
And if someone is there to specifically catch a person who is having an affair, you can safely assume that the smart glasses are just a distraction from the actual camera, and even if that isn't the case, you can safely assume that they would be photographed with a zoom lens from out on the street when they walk out of the building. So you're not preventing anything by keeping the smart glasses out.
Record as you like outside, but if you want to record in the dressing room at the gym, some people might not like that. Some might find it in their hearts to do you physical harm.
Agreed. But there's a difference between recording and merely wearing something capable of recording.
There is no practical difference between someone with a pair of smart glasses and someone wearing a cell phone on a holster or shoved down into the back pocket of their jeans with the camera pointed outwards.
As soon as you allow cameras of any kind, you've lost any real hope of preventing people from capturing video surreptitiously. The only thing preventing it is the owner's lack of any particular desire to be a creepy person and record people without their consent.
Thus, banning smart glasses, at least prima facie, seems like an arbitrary distinction that once again doesn't prevent anything.
I'm not saying I like the idea of smart glasses, particularly when they are sending images off device for facial recognition, because there's always some chance that someone will figure out a way to break into those data streams, throw a little AI at the problem, and catch accidental images of people doing private things, but concerns about the technical security of these devices involve a very different level of privacy risk than concerns about the actual owners of the devices using them to spy on other people. The first is an actual security concern that necessitates technical solutions like encryption, fuzz testing, using on-device models instead of uploading when possible, etc. The second borders on paranoid fantasy, because the devices don't enable the owners to do anything that they couldn't already do, making it both a fundamentally unsolvable and IMO entirely moot problem.
