alt Hacker NewsThe technology lives on, as Amazon "Just Walk Out". But rather than general grocery stores, it is used for concessions at stadiums and places like that.
I guess it turned out that the need more human intervention than they hoped, so the cost is too high for regular stores. However at places where a premium can be charged for high throughput or a low friction experience then the cost of the human intervention can be recouped.
Just a heads up that only the Amazon Go stores did the "just walk out" shopping thing. Amazon Fresh stores were pretty much just regular grocery stores. They had shopping carts with the self-checkout built in, but that was the extent of the technology.
