I think this whole topic is a beat-up. There is nothing here to debate. For a start, the talk should not be about "smart" glasses. Most of the glasses under debate are not smart at all. Just a camera that can be turned on or off. Simple technology that is not capable of any sort of smarts - certainly not blurring faces.

I genuinely don't see how we can legislate these things. They're out there and from a legal standpoint, are no different to any other camera you can buy. Even forgetting the 'smart' adjective and making the talk about glasses would be limiting. You can get cameras embedded into hats, necklaces, broaches/tiepins. Say you make all these illegal, how do you define them? Cameras you wear? suddenly the bodycams worn by the kids at Woolies or police are illegal. Go-Pros attached to your head/chest are illegal.

What if you have a shirt pocket, and the top of your phone is sticking out and recording. Are you going to make phone cameras illegal? I think this horse has bolted.
