I think that still, even using technology a talented person can create a beautiful piece of art unlike other person who is not talented and no matter what will come up with mediocre results.
As for the painted art, I think it all boils down to how unique it is and how it affects people. Great art should speak to people, move them, stir their emotions. I personally see a lot of nice pieces of art everywhere but they all seem to be nice, generic and not revolutionary. How many more "copies" of Monet or Degas do we really need?
