Just over half of Amazon Fresh stores are equipped with Just Walk Out. The technology allows customers to skip checkout altogether by scanning a QR code when they enter the store. Though it seemed completely automated, Just Walk Out relied on more than 1,000 people in India watching and labeling videos to ensure accurate checkouts. The cashiers were simply moved off-site, and they watched you as you shopped.
This is what really blackpilled me on the "AI boom". It would have a lot of problems even if it was exactly what it says it is, but in practice in many cases it's another avenue for outsourcing/unequal exchange.
