Also makes a difference if you publish those pictures or videos.

Yeah, I'm not as fussed over having laws on books, but on whether those laws are realistically enforceable. Like I recall reading at some point that lots of jurisdictions in the states define things like Orgies as a group of three or more people in a private dwelling without shoes on, based on ancient prudish attempts to describe what goes on. That's a law that's "on the books", but practically unenforceable.

Same sort of thought pattern, to me, generally applies to the recording of people in public. It's practically implausible that govt can enforce it uniformly, and it's on the books just so they can 'throw another book' at a perp who's been arrested for far greater offenses. There are also potential issues with 'two party consent' type recording setups, where one party is wanting to document events for legitimate reasons (recording an interaction with police, to CYA).

Idk. People taking pictures / recording public 'things', doesn't seem like a practical area for privacy legislation to come in overly heavy handed on.

It's pretty easy to just put a phone in a shirt pocket with the camera rolling as a sort of poor man's bodycam.

One of the issues is that there are legitimate uses for the tech. Like there was a post recently of a girl with hearing disabilities, ecstatic that she'd gotten glasses that provide real-time subtitles to people she talks to. A business / space with a "No Smart Glasses" policy, could essentially be denying people with disabilities access, which could land them in hot water just the same as allowing unfettered smart glass recordings.

Having them become more ubiquitous will also likely have severe impact on regular day to day interactions, even outside of the pervo-sphere. Talking with friends, or even interactions with other parties, can become a lot more complicated when people can record every word, can take those exchanges out of context, and use them against you in things like court proceedings. Eg. friends will often embellish comments/positions a bit for dramatic effect / story-telling purposes, with an understanding that it's not got to be perfectly accurate / you're going to be held accountable for every phrase. So you're right, that the more 'obvious' recording setup of phones limits this risk a bit... but not for long.

Yeah, I'd stopped short of noting that it'd prolly be more realistic to enforce regulations on wide-spread sharing / social media hosting of such content. Like in some ways, recording someone in public for whatever reason seems reasonable -- recording interactions with police, for example, being an area that makes a good deal of sense -- but posting those recordings, especially with the implied 'hope' that they go viral / generate notoriety and/or monetized returns, is pretty dicey.
