Whatever Happened to Amazon Go?

Remember Amazon (NASDAQ: AMZN) Go?

Launched nearly a year ago, this concept store was supposed to represent the future of retail. The Seattle location was outfitted with a network of cameras and other devices to automatically detect what customers took off the shelves and charge them through a smartphone app.

It was a quintessentially Amazonian vision, an experiment that leveraged technology to make the retail experience easier and more efficient. Notably, the 2,000 square-foot convenience store did not even have cashiers, an innovation that caused economists to decry the millions of cashiers that could soon become obsolete. Amazon billed the technology "Just Walk Out," and Amazon promoted the store as having no lines and no checkouts.
