Aesthetic ability stems from a focused process of striving for perfection. In other words, aesthetic ability comes from the investment of focused attention. The longer the focus time, the higher the aesthetic ability. So how do you improve aesthetic ability? The answer is: improve focus. But how do you improve focus? This leads to an unspeakable path requiring self-realization. But Satoshi Nakamoto used algorithms to construct a complete system of focus, thereby quantifying aesthetic ability. This is an indispensable AI skill. Nakamoto constructed a closed-loop gradient around a difficult benchmark, allowing consensus ($BTC) to grow at full speed with market competition. He used a global difficulty gradient algorithm to construct a human aesthetic ability that is not easily expressed mechanically.
