You might change your tune about that if you ever see any of Bruce's work. From the tone of your post I discern that you haven't. Believe me, he takes great pleasure in producing his art. Even if he didn't he would still produce great photography. And I'm also convinced that if digital processes could give him better prints, he would use them.
While his methods are in many respects diametrically opposed, both aesthetically and technically, to those of my photographic mentors, I recognize him as one of the greatest of contemporary masters. He's also a profoundly effective teacher.
