From The Verge:
By the end of the day, I had become more interested in asking people what they thought Glass was doing instead of delivering my little speech about what it actually did. Almost everyone thought it was on all the time, displaying ambient information or augmenting my entire field of view. One person told me she thought I was disabled and it was a new kind of prosthetic vision device.
But everyone universally assumed Glass was always connected to Google’s servers, collecting video and other data in order to return useful information to the display in real time. That’s the intuitive payoff to always wearing a display and camera on your head — a payoff so enormous it would conquer modesty and send me charging down the stairs to that hotel bar without a second’s hesitation.
But in order for Glass to deliver that payoff and succeed in its mission of becoming invisible, it has to become far more intrusive. Navigating the balance between utility and privacy is Google’s biggest existential challenge as a company, and it’s hard not to see Glass as the physical manifestation of that struggle — the day Glass goes from being activity-based to ambiently aware is the day Google changes forever.
