This is idiotic opposition. Spy cameras exist. Bluetooth earpieces exist, Glass is interesting for what it receives (the server software integration) and for its HUD, not what it caputures and transmits.
I drink gallons of Google-Koolaid, but even I can see(pun intended?) that Google glasses is going to have some social issues. Even I will be a bit uneasy talking to someone wearing them.
Google Glass will make recording others openly acceptable. Spy cameras and earpieces don't exist with the intention of ubiquitous use while Glass does.
Can you imagine everyone you know who wears glasses now using a camera at all times?
Google Glass will make recording others openly acceptable.
Or it will result in a literally violent backlash against constant privacy invasion.
Or hopefully something in between, like the village who just ran the Google Street View car out of town when they heard it was coming (though it was disappointing to hear that Google later went back and got the footage anyway).
Mass surveillance is not OK, and is a Pandora's box situation where once the data is out there, realistically it's never getting deleted again. Privacy has evolved as a valued concept in just about every civilised society for good reasons. It's just a shame that a generation of Facebook addicts are too busy getting their hit to notice all the negative consequences to the kind of culture they're inviting.
Many people are interested in Glass as a heads-up display or wearable computer, not as a camera. "Many" may end up being a very small number, but it stands to reason that it's larger than the number of people that actively desire to record strangers.
Unfortunately, the current model requires both a microphone (to hear you) and a camera (to see gestures), so even well-intentioned users will still be brandishing recording devices in ways that make others uncomfortable.
Maybe for the wearer that's interesting, there's no such distinction to the people being recorded; they can't see what the wearer is up to with the device.
