How many music streaming services and digital downloads of mp3 and flacs remain playable on only certain hardware?
The music digital space is much more open than console games, which will only work on very specific hardware. And DRM free downloads. Music is one space that is surprisingly pro consumer when it comes to compatibility and control of purchases.
If consoles were as open as PCs, being able to install any OS and programs on it then physical shift would be less of an issue on consoles. Consoles are so locked down they can get away with paywalling multiplayer, and even jailbreak can't really bypass that.
Whether its meta or not, discrete wearable video recording is not something I am in favor of. Like the recent LG spyware installing on people's Windows PC shows, many tech companies aren't in the business of being privacy respecting in the products they offer. It's usually those companies that gain market share.
And individuals with how quick they are to live stream and share every picture and video voluntarily to social media sites doesn't much lend to responsible use either. At least those people aren't usually hiding that they are recording.
When it comes to legal audio wiretapping those are already sufficient in places where it is legal to be used in cases like yours. So I don't much see a need to further extend hidden audio recordings to also include hidden video recordings with wearables. Cases where video is also needed seem more like very specific niche cases involving investigations, so to shift it to being an every day casual accessory I dont see as necessary.
