I disagree quite a bit. For me the medium, the technique, the process is all part of the art. Yet I still think the end result is also critical. But coming up with create ways to produce art matters.

And I am confused about the “doing it any other way”? I don’t really see other ways to achieve the same result. Say painting and photography will both produce end results that are quite different. The skills are very different. The end material is also quite different. The same way stained glass is quite different from painting
