Plus it becomes impossible to get multiple developers to work on the code if they can’t understand it because of its messiness, so there’s a bit of survivor’s bias and stronger motivation to clean the code up to be comprehensible to others when you have multiple people working on it. Also, I feel personally attacked by the headline. :) It is for this reason I try to keep my code and models pretty simple, only two or three pages of code (or ideally a single page), and I don’t try to do too many things with one program, and I choose implementations and algorithms that are simpler to implement to make concise code feasible (sometimes at the expense of speed or generality).
