THIS. A million times this. The world is about solving real user problems. And obviously this code solves a huge 20M USD problem. And the code is obviously so good, that even 3 "bozos" (to use your language) can manage and maintain in for decades. This is the holy grail. I wouldn't change a thing and instead ask: how can you make this generate 40M USD a year? This is how you will add real value to the company, and management will love you.
