While the first part of this article couldn't decide whether it was directed toward technical or non-technical audience, second part about security implications of such an easy way to get root was definitely thought-provoking. While I was super-eager to get Glass before, it really got me wondering if having camera and microphone in your glasses is such an great idea after all.
Yes it's a great idea. Microphones are already a standard part of widely accepted headphones/headsets. Cameras aren't as accepted yet but they will be, whether that's in 2015 or 2025 is the 64 billion dollar question.
I agree with your statement that cameras will be accepted in the future, but I'm not sure it follows that it's a great idea.
On the other hand, I'm not even convinced cellphones and facebook are great ideas, so my life is probably not representative. (Now get off my lawn.)
