Changes at Amazon Fresh

I've never shopped at Amazon Fresh stores, but I'm disturbed reading about the experience. It's like discovering that hamsters power your car. Apparently the "Just Walk Out" technology worked through intense surveillance. All sorts of people in India carefully watched exactly what you put in your shopping cart. And now Amazon Dash Carts will do the job instead. Powered by hamsters, perhaps? And what are the motives of these hamsters?:

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.
