Code Is Your Partner in Thought

Writing about the buildup of technical debt, Ward Cunningham said, “Although immature code may work fine and be completely acceptable to the customer, excess quantities will make a program unmasterable, leading to extreme specialization of programmers and finally an inflexible product.” In this article, I’ll dig into the apparent paradox: how can code work fine and yet be unmasterable? Our code has characteristics of both a machine and pure thought. Technical debt arises when these do not line up. Software developers have a hard time seeing how weird this is because we’re too familiar with our subject. To help us see it from a nonprogrammer perspective, I’m going to try something a bit different in this column. What follows is a fictional conversation between me and a nonprogrammer friend.
