Picasso once noted that “when art critics get together they talk about Form and Structure and Meaning. When artists get together they talk about where you can buy cheap turpentine.” When you practice a craft you become skilled and knowledgeable in two areas: the stuff the craft produces, and the processes used to create it. And the second kind of expertise accumulates much faster. I call this the turpentine effect. Under normal circumstances, the turpentine effect only has minor consequences. At best, you become a more thoughtful practitioner of your craft, and at worst, you procrastinate a little, shopping for turpentine rather than painting. But there are trades where tool-making and tool-use involve exactly the same skills, which has interesting consequences. Programming, teaching, writing and mechanical engineering are all such trades.
