one of the things I hate about art criticism is when someone says "anyone could do that!" - yeah, but they did and you didn't, that's why it's art
This is also the canned response though, we need to go up a galaxy brain level, transcend the opposition instead of taking sides.
I think what "My kid could do that!" folks are saying is that the technical skill involved is low, and this confuses them, why something is heralded as special which seems to require no special aptitude
I think what "But they didn't think of it!" folks are saying is that the real skill they + the conceptual art world care about is making a move in a game, and situating yourself—both choosing the right move, and conceptualizing it properly—that this is what makes the work "special," the social-conceptual accomplishment and not the technical one.
I think what "My kid could do that!" folks would say is, "Well why do I care about the art world's insider baseball game?" Bourdieu calls this an "autonomous field"—the performers are performing for themselves and for their friends, who are also performers or embedded in the tradition.
I think what "But they didn't think of it!" folks would say is, "Well I do,
I find it interesting and provocative"—and at this point there's really no recourse, just different preferences.
"My kid could do that!" folks would say, "Art folks who claim this is interesting are engaging in
preference falsification; it's classic emperor's new clothes; there's nothing there, they just claim to like it." The problem is there's really no way to know, is there?
Because neither extreme is true: it's crazy to think there's some conspiracy of mass delusion among vizart folk, where they're all lying about what they like and find interesting. It's also crazy to think that what we find interesting isn't a social and performative phenomenon. It's not a question of "preference falsification" vs "true belief"—it's a question of how much preference falsification, and at how unconscious a level—or even the question of whether authentic, asocial preferences exist in the first place. (Or if it's all Girardian mimesis...)
