Interesting post, thank you for sharing!
With that said, this is extremely scary. Unavoidable and an obvious step on the technological evolution, but scary nonetheless. Cell phone camera apps already are recording way more than they should. With a technology like this, there is no privacy or secret that can't be broken by the companies that own the patents and obviously from hackers. I am not willing to give away my privacy for convinience, but when you reach a point when everybody around you is using one such device, what does your privacy and what you want matters? Scary indeed...

"The right to swing my fist ends where the other man's nose begins." - will no longer be applicable in the future. Does that mean individual freedom wont be applicable in the future aswell?? Only time will tell, but it sure looks that way.
