Technology is replacing so many of our manual tasks and AI and Robotics in the future will replace a lot of more. Even now, my handwriting is terrible because i usually type instead of handwritten. We dont have to walk even today. They already have driverless cars. You know muscles you dont use, you lose. In the future we may evolve not only to be digitless but also the ability to walk. Maybe we are headed to just evolve to pure energy. No body just like a ghost, dark matter, photons/light etc. Or i predict evolution will favor those whose ancestors were more physically engaged not always by conscious choice and they will be the elite and the rest will be considered less evolved like vegetables or like animals to them. The tables will turn like how the elite became weak having too much done for them where those who did for them became more clever, knowledgeable and capable. Better start writing, cooking, jogging, sew your own clothes, washing clothes at the creek, stop using that calculator/ do math in the head, take stairs not elevator etc. Hurry before its too late. Lol Having tasks taken away from people to take care of themselves disempowers them but alternately humans doing assembly line monotonous physical work makes them stupid or vegetable like too. So its a mixed bag.
