As someone who paints daily and has made a lifetime study of painting, including visiting museums locally and worldwide, as well as trying to stay abreast of the "state of the art" of the use of computers in art (as well as writing software as a day job for decades), I am puzzled by this statement.

The greatest paintings, "in the flesh," simply have a punch and an impact that, to my eyes, has not been rivaled by the "state of the art" in digital renderings of any kind, or indeed in any works where a mechanical process is anything but a small factor in the completed work.

I would be fascinated to see what you consider to be examples of "automated computer-generated art" that rivals the works of Rembrandt, Titian, Velazquez, or anyone in the top tier of art history. Those artists are world-famous (not just now, but for centuries) for a reason, but you often have to get in the same room with the works to see why.
