> There is no “simplifying force” acting on the code base other than deliberate choices that you make. Simplifying takes effort, and people are too often in a hurry.

There is a simplifying force: the engineers on the project who care about long-term productivity. Work to simplify the code is rarely tracked or rewarded, which is a problem across our industry. Most codebases I've worked in had some large low-hanging-fruit for increasing team productivity, but it's hard to show the impact of that work so it never gets done.

We need an objective metric of codebase cognitive complexity. Then folks can take credit for making the number go down.
