When you think about it, you're allowed to walk in anywhere. Look at whatever you like. Listen to whatever conversation you want to. This is well and truly already established. Now that someone can remember everything they see and hear, suddenly we're talking about privacy issues. Lol.
When I think about it, I can see a clear difference.
There were all manner of places where human eyes were accepted, but still/video cameras were not, long predating "smart glasses". From changing rooms, saunas, locker rooms, and bath houses to performances like plays and concerts, and movie theatres to executive board room meetings, and even court rooms in many cases.
There are lots of scenarios where everybody accepts and consents that other people will see/hear them, but do not accept or consent to be recorded.
Are you really incapable of seeing the multiple clear and obvious differences between "seeing/hearing something" and "recording something" ?
