I think the author is arguing for a cultural shift that has already happened. During my 4 semester co-op readability and maintainability was the single largest concern. All commits were code reviewed and it usually took 3-4 iterations to make everyone happy. I learned a ton about why best practices were best practices and how you could structure code to make it more intuitive and less prone to misuse.
I hang around the gamedev.stackexchange a lot. All the senior members value taking extra time to make readable and reusable code. I don’t get told "once it works, the code is right" I get told take your time and make a reusable understandable block of code.
Even at the very large corporation that I work at now where I’m stuck using XP and IE 7 there is a large emphasis on making sure the code is readable and maintainable.
In my short career no one has ever told me getting it working and move on. Everyone has told me that I should strive for the code I write to be easily readable and maintainable by a new hire.
