This gave me an idea - what if we made a stable diffusion based AI that would replace unimportant faces (and possibly other identifying details) with different ones - I have seen that AI can do this and make the change unnoticeable.
That way people would be safe from having their personal likeness and whereabouts accidentally plastered over the internet (except when they want their photo to be taken), and the end result wouldn't look so obviously modified as blurring faces or licence plates.
