Back in the Renaissance, when perspectival drawing was being invented, that is art. But now if you draw a perspective, that is just representation, not art. When Van Gogh created canvasses of painted dots that coalesce into wondrous scenery, that is art, it made us see the world differently, changing our understanding of how reality can be represented not just as direct visuals but that our brain can make the leap. And even an artist like Marcel Duchamp, who many regular people struggle with to understand or see value in, when he leaned a vacuum against a wall and put it in a museum, that is art, because he was making us think about the role of museums and objects, by using the tools of curatorship, namely the selection of objects and placement in a museum.
