Onto the question of virtuosity, which I find quite urgent in this debate. I am also surprised that it has not been brought up before. Practicing artists mediate their ideas through tools and the latitude of expression permitted by these tools. Whether the tools are a paint brush, an electric guitar, a video camera or the latest workstation is largely beside the point. When a technological shift occurs, the only thing that changes is the bar moves, laterally or vertically, to a different position.
Transcendence occupies a different plane.
From there, it is on to other hopefully more insteresting things. And, as you said, much of this comes back to virtuosity. The ultimate, and for me desirable, absence of technical reference. I have experienced this connundrum quite frequently, in both my professional life and my teaching life. This is true of the banjo, the editing suite and the computer program.
