Amazon Introducing “Grab and Go” Grocery Stores: Epic or Horrible Idea?

Imagine walking into a grocery store, taking everything you need, and simply walking out without going through the checkout stand. That is the premise of “Amazon Go”, using app technology “much like you’d find in self-driving cars.” Watch this video from “AmazonGo” that explains it all, and let us know what you think of this. This would help employers by eliminating the need for thousands of jobs (cashiers, baggers, etc) but of course that is a downfall as well, hurting the (already hurting) job market.
So what do you think–is this epic and cutting-edge, or is it edging even closer into a full-on “Big Brother” world?
