You read far too much into my word choice. I think you could substitute any technical profession (I would include everything you mentioned explicitly) for "engineer" and what I wrote would be equivalently true. I just happen to have the most direct experience with engineers, and the original article was about engineers.
It's true of the technical aspects of art too: professional musicians rehearsing, for example. It's less true when you get into the ingantible parts of art, though... taste is inherently personal.
