▍原文
Amazon is giving up on the cashier-less "Just Walk Out" technology at its grocery stores.
The technology was supposed to let customers grab what they wanted and just leave, skipping any kind of checkout process. Amazon wanted to track what customers took with them purely via AI-powered video surveillance.
However, a report revealed that "Amazon had more than 1,000 people in India whose job included manually reviewing transactions and labeling images from videos."
