The reality is that we likely don't need any new devices as much as people want to keep saying that. If you have airpods and a phone you could talk to chatgpt and say "show me how to fix my kid's bike with a simple video on my phone" -- it buzzes your phone and boom the video is there. Sure it is missing the ability to take a picture of the world / video -- so in that case, a pair of the meta rayban glasses would do that -- again just use your phone / cloud, it all works. Or skip the special glasses and hold your phone up to the thing you want to take a picture of. No need for magical new devices.
Having a camera staring at me while I talk to somebody -- yea I'm gonna pass on that.
