Interesting, but did this include web code and code only one person really ever works on?

Because on the pure backend level, I have observed the reverse over my career. The shorter, the "smarter", the "cooler" the code, the more buggy it is. Not based on the code itself, but based on the developer inevitably leaving the company at some point. Meaning that what matters all of is a sudden is how verbose, how documented and how explicit the code is, because the bugs come from someone else messing with it as they get to take it over. It's a legacy problem in a lot of ways.

Hence me saying that if solo projects are included, they probably tilt this massively as they'll never really run into this problem. Like say, you just scan github or something. Of course most projects in there are solo, of course the more lines the more room for bugs.
But in an environment where you're not solo coding, the issue is not getting the code to run and having it have no programmed bugs, but to be able to have someone else understand what you did and wanted to do in a meaningful amount of time, especially as they have to mutate your code over years and decades. Or maybe it's just that the bugs no longer are what "matters", as fixing code bugs is cheap compared to the endless hours wasted from "clever" code being unmaintainable. 🤷
