A friend of mine got a pair, they get this light when theyre in use but you can't quickly tell what's happening. Are they taking a picture, a video, or just conversing with the AI?

I find it annoying, ofc, he's my friend so I could tell him not to take "candid pictures" of me (I generally just don't like people taking pictures of me).

But you would have no control whatsoever on the street and it would be very difficult to know that someone you've passed on the street has or hasn't taken a picture of you.
