Initially, efficiency and effectiveness are in sync, tracking each other's progress. In the process of learning, we write how-tos to skills. We transmit these through training and education. But, it is then, when language enters, that we start losing understanding and clarity.
Protocols outsource understanding, so we will not realize our diminishing effectiveness without active thinking, as reality changes and we need to update protocols continuously. In this space of divergence, opportunities in language and self-authorship come up. Continuous authorship helps with the fallacy of complete knowledge and improves innovation.
