But UK supermarkets can be up to 185,500 sq ft and questions remain about how long it will take before Amazon or any of its rivals' technologies can be reliably deployed at such scale.Simpler technologies to reduce the need for staffed checkouts include portable barcode scanners and tills that allow shoppers to ring up their own items.Advocates of such tech suggest it frees up workers to perform more interesting tasks.Amazon's own site says: "Retailers will still employ store associates to greet and answer shoppers' questions, stock the shelves, check IDs for the purchasing of certain goods, and more - their roles have simply shifted to focus on more valuable activities."Image copyrightGetty ImagesImage caption Amazon Go shops encourage visitors to bag their goods as they go Ms Berg said: "Ultimately, there will be fewer jobs as automation comes in."But [those that remain] will focus on more customer-facing tasks and should provide a better experience to customers."And from that point of view, the skills required across the retail sector are going to evolve massively over the next decade."
