I like your sentiment but you are here on HN so assuming you are somewhere with food and an internet connection. Life is good. I see people around me begging on Facebook from the public library internet connection for cans to return so they can eat. They won’t care for one second about a human in the store they only care about getting the cheapest food they can. These automated stores I can really see being a hit especially if they can cut the costs of a regular store even by a small percentage.
