I mean, the resulting painting as done by Pollock or Mondriaan is pretty silly. Just splash some paint in a canvas, or draw some lines and use the "fill bucket tool" to create colored squares, right?
Yes, sure, it's about the process and about the inescapable context with postmodern conceptual art. Whether it's mere splashes I will leave aside, but Pollock and Mondrian precisely brought the consideration of the process to a new light, that's part of what makes them significant figures. Mondrian didn't have mspaint.exe, those geometries meant something different at the time. Also, I don't think Picasso would have been so infatuated by cubism if computers with triangle mesh rendering and solid modeling had been around.
