The innovation part is how this Go store has the power to bring healthy snacks into general convenience stores and gas stations and getting the disease causing ones to be pushed out.
Why are you patting Amazon so hard on the back over this hypothesis? The article didn't mention anything about it; Walmart, Target, 7-11 all have the exact same power, but don't exercise it. Why do you think Amazon Go will push healthy snacks over deep-fried candybars?
There's no evidence that Amazon bought Whole Foods because it's an upmarket grocery store and avoided others. It's very likely that Amazon will eventually buy a "normal" grocery chain and serve as large of a population as possible.
Huh? Amazon Go is a separate store from these places. There is nothing mentioned about how they're licensing their technology out to other vendors. And it's not innovating by offering healthier options for grab 'n go food and snacks. I don't see your point here.
