If a personal HUD was so great, why do they need to bundle an outfacing camera to the device at the same time?

A personal HUD with sufficient utility might gain acceptance by people not wearing the device. Coupled to an eye mounted 'recording other people without their consent' device and Google's servers though?

(And yes, my tone is indicative of a luddite stance in this particular instance)

A personal HUD with no way to be context sensitive (ie no camera) is dead in the water. I'm biased because Im working in this space. but, I believe context aware augmented reality is the killer app for wearables. Honestly, the people wearing Glass aren't recording you, Google isn't recording you; if you're worried about privacy concerns it's the last thing on the list of things to be terrified about (just an anecdote, my little sister spends an inordinate amount of time subtly snap chatting images of the people around her with her iphone so, odds are your dystopian future of you describe already exists). So long as we are given root access and the option to use our own servers and software, the hardware advances are not the problem. Acting like a Luddite will not protect your privacy.

The utility proposition of a HUD has always included data display relevant to what is in the field of vision; that's why HUDs are traditionally tied to sensor systems, whether its Glass and its camera or a jet fighter HUD and the targeting radar.
