Commodity
The use of tools to generate "art" is simply making the work a commodity. In contrast, usually "art" is created by a closed group of craftsmen. Now any one can start typing and generate as they please.
Just like the article states, the photographer is more than a button pusher. A musician is more than playing that old or classic instrument. Just like a real artist is more than putting streaks on a canvas. But complaining that a new group now has access to creating "art" is like saying that inventing the wheel destroyed the manual labourers' work carrying stuff.
I for one would be very happy to use these new tools (yes, they are tools). My artistic drawing skills are abysmal, but my descriptive ability and programming are reasonable and fine. Now I too can make nice images for projects that can be improved with some nice images.
