Almost too many things to respond to
First, I think this thread is really about technology and art, not science and art.
Second, the WSJ article is pretty superficial and its emphasis isn't so much the differences between science, technology and invention (although it does explain them reasonably well in simplistic terms) as the consequences, but when I posted awhile back on the lagging of science behind technology that was exactly my concern as well.
Third, to answer amir's question (which I overlooked since I was hurrying out the door) I'm not sure any of what you describe is really science, although perhaps with more details either of your examples could be (or not).
Last, there is nothing wrong with being an inventor or "technology guy", as long as everyone realizes that we can build and measure things which we don't really understand.
