A store that you appreciate is build around the products and knowledge that the owners and staff provide, but removing the checkout line isn't going to change that. There's no reason this tech can't proliferate and become as cheap as barcode scanners. Having people less focused on scanning the products and more focused on communicating with customers and helping them find the exact product they want makes a whole lot of sense to me.
