I'm assuming that the position on the shelf has very little to do with adding the item to the cart. I'm guessing that taking the item out of range of a scanner and into range of your phone is what does it. I've not seen anyone so far suggest that people will still work at the store. There will still be people who help customers do what they need, but instead of mindlessly scanning groceries, they'll be there for the things people actually need help with. Returns, price problems, finding things, lifting heavy items, etc.
