It seems like a more polite way of handling this in private spaces is just to ask that people take them off - just like we do when a pig farmer walks into our house with their boots on.

I get why people are creeped out by them, but we get filmed or photographed hundreds of times a day in a big city when we are in public spaces. Gatekeeping a potentially useful technology for being filmed in public -- well, everyone is _already_ filmed in public. ATM cameras, stoplight cameras, drone cameras, smartphone cameras, security cameras, doorbell cameras. You are on camera every time you step out of your house. You are on camera every time you open your work computer. Singling out cameras in eyeglasses as "creepy" is kind of worrying about a drop in the ocean. Cameras on self-driving cars. Nanny cams. Closed-circuit cameras. The things are everywhere, and they are always invasions of privacy. Why is the line the "creeper" glasses?

I'd be ok with it if we were for banning all non-consensual recordings in all spaces. But we're very much not.

And if we're not, then having a personal heads-up display that is contextual to your current surroundings or has augmented reality capability is too useful to not use (eventually). I'm bad with names, and good with faces. That use-case alone would be worth it for me, if it were available.
