I think investors like Amazon taking shots like this? It was never a broad roll-out, 43 stores is micro-scale for Amazon.
Still, would love to see a breakdown of why it didn't improve. Regardless of the accuracy at launch, I'd think that advances in AI would have been massively to their advantage. I wonder if security degradation hit them hard.
The entire system depends on a level of social trust that doesn't exist in American cities today. Similarly, the "Dash Cart" seems like a cheaper and easier way to accomplish the same thing.
At the end of the day, there's also a mismatch in the use case. If I'm going to a smaller format store, like they had, I'm not buying a ton of stuff. Self checkout is great, and minimal friction.
I'd think that improving the UX of self-checkout gets 80% of the way there with way less fraud, way less theft, and way less technology.
Still, I think it's wicked cool they took a big shot.
I know someone that worked on the project in the early days. It was always incredibly difficult technology, they were always behind on their accuracy targets, and the solutions were increasingly kludgy as they layered more and more complex systems on top. An honorable failure.
A lot of smart people really tried to make it work.
