"Would you like to sign in with your palm?" That was the question a cheerful Amazon employee posed when greeting me last week at the opening of a Whole Foods Market in Washington's Glover Park neighborhood. For the next 30 minutes, I shopped. Then I simply walked out, no cashier necessary. Whole Foods or rather Amazon " would bill my account later. More than four years ago, Amazon bought Whole Foods for $13 billion. Now the Amazon-ification of the grocery chain is physically complete. Amazon designed my local grocer to be almost completely run by tracking and robotic tools for the first time. The technology, known as Just Walk Out, consists of hundreds of cameras with a god's-eye view of customers. Sensors are placed under each apple, carton of oatmeal and boule of multigrain bread. Deep-learning software analyzes the shopping activity to detect patterns and increase the accuracy of its charges. The Whole Foods in Glover Park ... has sparked a spirited local debate, with residents sparring on the Nextdoor community app and a neighborhood email list over the store's "dystopian" feeling versus its "impressive technology." Some ... said they had found errors in their bills and complained about the end of produce by the pound. Everything is now offered per item, bundle or box. Some mourned the disappearance of the checkout line, where they perused magazines. Many were suspicious of the tracking tech. "It's like George Orwell's '1984,'" said Allen Hengst, 72, a retired librarian.
