Am I the only one who wants to see these things banned in most public places?
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.
Historically, body-worn hidden cameras have been for perverts, spies and journalists. Normal folks don't mind people knowing they're taking a photo, and want to be able to frame the photo and suchlike. Gopros would be clearly visible, front and centre on people's helmets - and only while doing sports. Guards and cops with body cameras want people to know they've got a camera, as a deterrent.
You'd occasionally see hidden camera footage used by investigative journalists - but outside of that, the market for body-worn hidden cameras was mostly weird lonely pervs who wanted to take photos at the topless beach and upskirt photos without getting into trouble.
A glasses-camera product won't succeed among us normal folk if wearing it makes you look like a weird lonely perv.
You say this, and yet as a blind user of the Meta glasses (they're actually great for accessibility!) I am not ... seeing it. They are far more ubiquitous and warn by far more people than you would expect, especially when comparing to Google Glass.
If this were pushed by Apple, people would be responding much differently, since there is an inherent level of trust in regards to Apple's privacy protections, vs Meta.
So, not so much the technology, but rather the trust (or lack thereof) behind the implementor.
