Amazon’s automated 'Just Walk Out' technology, initially touted as an AI-powered checkout system, was actually reliant on human reviewers in India.

Just Walk Out aimed to allow customers to bypass traditional checkouts by using cameras and sensors to track their purchases, and leave without checking out as they would get receipts afterwards. 

The system was supposed to save retailers money through 'operational efficencies'. 

However, the company was found to be quietly using approximately 1,000 'Machine learning data associates' in India to monitor customer transactions and label video footage to train the system’s machine learning model, resulting in accusations of opacity, hype and hypocrisy. 

Amazon was also accused of undercutting US workers.
