Does one get smarter with age? How about with if one is repeating the same skill/task many times. Does this make them better.
Another way to think about this is: one becomes less ignorant with time.
This is quite a paradigm shift in thinking. The knowledge did not change, neither did the content. We just become less stupid about it. It is like peeling an onion. The layers are many, but with every peel off, we get closer to the core. We become less ignorant.
