Amazon Go pioneers grocery shopping without checkout lines, cashier jobs

On Monday morning, Amazon unveiled its new vision for the future of brick-and-mortar grocery stores: Amazon Go. The new service offered by the online-shopping colossus allows customers to walk into the store, grab what they want and simply leave the building -- without interacting with another human being or waiting in line. Amazon says the company brought together the most advanced machine learning and artificial intelligence to eliminate cash registers in a new 1,800-square-foot store in Seattle. Amazon Go is already open to Amazon employees through its beta program and is scheduled to open to the public in early 2017. As seen in a video released by the company, shoppers scan a code from the Amazon Go app on their smartphones at a kiosk and then proceed to fill up their carts.
