They were killed in part by their recording feature. I will not approach a glasshole, and most certainly will not talk to them until the gadget is safely turned off and removed. It's my choice.
Being a relatively peaceful person, I will not hit a glasshole for him merely existing near me; however plenty of people, especially in drinking establishments, and especially in various states of inebriation, may not feel so constrained.
The gadget may find widespread use in the industry, where it can be operated for a well defined purpose and without a threat to privacy (there is little of that at work, and you don't wear it away from your station.) Businesses will not want to stream anything to Google, and they will not even enable the camera, as there is rarely a need to stream video in real time - except surgeons, for example, who teach others or are monitored by their teachers. A mechanic, for example, could enjoy an easily visible, large drawing of the device in the virtual screen of the GG. Most of the data would be coming into the GG. Even when specifics of the job (assembly of high value, high cost of error items, like space hardware) require recording, one could record on an SD Flash card - there is absolutely no reason to transmit the video over a radio link. Same applies to police officers. If the recordings have limited access, there is not as much threat to privacy as when they are streamed to Google.
No, the record feature only bothers people who haven’t been paying attention to how the world works now. My favorite “glass” incidents involve people confronting the wearer for possibly recording them WHILE recording the whole incident on THEIR phones. We are in the post privacy world, if you are in public you ARE being recorded, by multiple items, and if you do anything even a little interesting it’ll land on youtube.
As soon as it can replace the phone rather than supplement it they’ll be a hit. Also it’ll help if the supplement prescription glasses rather than replace.
The cameras didn’t stream to google. They just sent it to your phone, where it would then go where ever you had told your phone to put data. That stream to google thing was just a myth. Although of course, since it’s part of a smartphone, there’s an app for that, though again it doesn’t go to google.
