I watched a kids face boggle, totaly transparent discomfort and incomprehension as I handed him the correct amount for my purchase at the grocery store.I do this regularly, carrying a good mix of bills and change, some of the checkout kids respond differently, and I see the light go on, and I get a grin, but the most common reaction is confusion, looking at the money, at the display, back and forth, counting the money, entering it, and even remarks like "it worked!" But lets face it, if you cant count, and do basic math in your head, or with pencil and paper, there are millions of potential tasks that are going to be much harder to do, just sipmle time management. The kicker is that if someone NEEDS to husle durring busy challenging events and time, nothing can or will be better than inate skills.So think about a societal/national crisis or challenge , the whole concept of automating basic thought processes is predicated on afluence and plenty, and a lasitude that never ends. Instead of some alien zombie apocalypse, it's a never ending garden party with milling slightly confused somewhat shabiliy dressed people expressing a general mild angst and triumph is to latch on to some biting enui, again.
