I cringe every time I see someone use the term "craft" in the context of computer programming. It feels like a desperate attempt to seek adoration as a "sub-genius" in a poorly understood field. Computer programming is hard because the platform is either poorly documented or changes very quickly. Too much of my professional work is about finding a "super hero" (their term, not mine) solution to a poorly documented problem. It is tiring, and not-at-all heroic. Coding bootcamps have taught us that when you tear down the gatekeeper walls, more people can write CRUD apps (that the world actually needs) than ever thought before.
As a counterpoint: Look at the history of the libxcb: https://en.wikipedia.org/wiki/XCB
[Bart] Massey and others have worked to prove key portions of XCB formally correct using Z notation.
