I have yet to understand how are these glasses useful to any normal people other than creeps? If you want to record simply use phone.
Where your pub might appear to you to be swords and sorcery world, with an orc for a bartender, the bartender would be in a sci-fi world and you would be a robot.
The cameras were needed to keep track of the real world.
I agree though, and this whole pervy use case wasn't really envisioned as much then.
This tech is the prototype for the future. Phones are outdated input devices and will be replaced in a decade or two.
