Since this is basically what Piggly Wiggly brought to the world of grocery retail in 1916, but with the customers replaced by robots (tee-hee), I wonder how long it will be before robots do the moving around of products at a supermarket near you? Whether I shop at a warehouse store, or I go to the big department store and or supermarket chain stores that are all evolving into the same kind of 150,000+ sq. ft. 'everything' store (i.e. warehouse stores with better product packaging and shinier floors), I can see that retailers are already doing warehouse-sized volume in cities all over the planet.
