Artificial intelligence-powered Amazon Go store opens in Seattle

People stand in a long line of shoppers waiting to get inside an Amazon Go store Monday, Jan. 22, 2018, in Seattle. More than a year after it introduced the concept, Amazon opened its artificial intelligence-powered Amazon Go store in downtown Seattle on Monday. The store on the bottom floor of the company's Seattle headquarters allows shoppers to scan their smartphone with the Amazon Go app at a turnstile, pick out the items they want and leave.
