I’ve had the opportunity to work with lots of mechanical engineering corps to date, and I can confidently tell you: Even if they had some platonic ideal, they would never be able to follow through. The mediocrity of their software development practices is… profound. On all levels of the hierarchy. Sure they care about the ideal of sustainable software development, but they just can’t do it.

On the other hand, my employer advertises clean code as a service, and this attracts the kind of developers you describe.
