It reminds me also of the eternal "can we separate the art from the artist" debate, too. For instance, some people (myself included) find that their experience of some art that they previously enjoyed is soured when they learn that whoever made it is a Bad Person in some way. Neil Gaiman comes to mind as a recent example.
I think it goes beyond just creative people being more interested in the process behind the art. Even people who are more purely consumers care about where this thing that touches them came from. I think a person's experience of the art makes them feel closer to or entwined with that artist, even if they might be long-deceased. Or non-human?
