The author's statement that "My view is that applications are a social construction" I think hints at a deeper truth, that while _code_ is run by machines, managing a _codebase_ is more like raising a plant in a garden and not like changing the oil in a machine. Reminds me of "A Codebase is An Organism"[1].
