This is a little bit related to the separate issues of education and training. One is more related to things that should not change too often, like logic and science and the other is related to the effective use of some specific methods and technology being used at some point in time.
The effective use of evolving methods and technologies will require continual training but of course that does not guarantee positive results if those methods and technologies are not based on a valid science for the problem at hand. The approach can be wrong or even the science can be wrong. This happens on all professions and therefore there is the requirement for continuous upgrading.
I am not a colour scientist. I am an engineer. I might be oversimplifying the whole issue of colour management but I see it as having clear failures in the logic used to solve the problem. In my limited view, I see that colour science has little to do with developing simple and effective methods to obtain reasonably predictable and consistent colour across multiple printing processes.
