A CS degree also qualifies you for on-the-job training in writing code, that odious task that your professors find trivial but somehow are also terrible at it.

We just don't have time. Incentives are elsewhere. Any time devoted to writing good code for a paper is time we cannot use to work on the next paper, (shudder) grant application, or a plethora of other things that we are either forced or incentivized to do.

I miss coding from when I was in a more junior stage of my career and could afford time for it, and I think my fellow professors mostly feel the same, I don't think many would dismiss it as trivial or odious.

I’m inferring “odious” from the priority that is applied to it. Maybe “irrelevant” is better?

But when those junior engineers hit my company, they can do homework problems and that’s about it. “CS fundamentals” aren’t useful when you can’t quit vi or debug a regex. They get to be useful 2-3 years later, after the engineer has shaken off being a student.
