RE: Amazon Go - Will checkout-free stores become mainstream?

This will be very interesting the first time I get a chance to do it, but it just makes so much sense. I love when technology is implemented in a way that simplifies our lives. So much of what we do is so much more complex than it would need to be in a perfect society. I'm talking about 3rd party verification, security procedures, etc etc. As the tech grows, so much of that will just be happening in the background without us even having to worry about it. It will sure be a balancing act though between convenience and big brother's control.
