It would seem that Dada, in its proliferation, automatically was doomed to failure. Being that its message was "anti-art", its elevation and celebration by the art world seems to automatically subvert its ideals, turning deliberately non-art into things worthy of being bought and sold for zillions of dollars and refuting the claim that art is, in fact, dead. Of course, maybe they were just very clever businessmen... But that sounds more like Pop art to me.
