Nice analogy! Although really, when they get D centers to run like automatic milking machines, we'll all probably be better off. The local paper just did a big article about the new automated systems. When ever the cow feels like it wants to be milked, it walks up to the machine. It automatically recognizes the cow by its id tag, adjusts the machine to the proper settings, starts, cleans and sterilizes, hooks ups, milks and releases the cow within minutes. The cows can go whenever they want, and as often as they want. Some go twice a day, some up to 6 times.
