Fantastic book called "About Time" by physicist Paul Davies is a great introduction to some of this.

Ring as a company, and the CEO or inventor, is full on pro police having access to your account-it was this way before Amazon bought it and I don't really care, but some of you may want to Google it and get more info. I read an in depth article, and have no idea where it was, but if you're concerned about your civil liberties I wouldn't use Ring. They can't get me for shit so doesn't matter to me.
