From a Washington Post story by Caroline O’Donovan headlined “Amazon grew relentlessly. Now it’s getting lean.”:

SAN FRANCISCO — Once, the busy office workers and passing tourists here could swipe their Amazon app, grab a granola bar, a premade sandwich or a soda, and walk away without ever interacting with a cashier.

But now the e-commerce giant is shuttering all of its automated Amazon Go convenience stores in San Francisco, which represented an expensive gamble on a futuristic system of sensors known as Just Walk Out technology.
