For some reason I take comfort in knowing that there are still aviation jobs that have a high degree of craft (art). According to this article, a lot of the training is by apprenticeship (copiloting), which was the only way to learn flying in the 1930s.
Most of my aviation research emphasizes how craft skills are becoming less important. And indeed there is also a lot of procedural science in mosquito spraying. But in a variety of high-variety, high-risk aviation, expertise is still key. Other examples are bush flying and low-altitude military flying.
