I mean, senior researchers in stable roles don't really do any better. Just to pick the first example off the top of my head - one of the investigators I worked with, during my year as a staff member of an academic institution most of a decade ago, is also one of my oldest friends; he's been a researcher there for what must be well past ten years by now. Despite one of his undergrad degrees being actually in CS, I still find ample reason whenever I see it to give him a hard time about the maintainability of his code. Like I said before, it's a field in which people really just don't give a damn about engineering. Which is fair! There's little reason why they should, as far as I've ever been able to see.
