Greg Allen points out that Washington Post critic Blake Gopnik made a mistake. I’m not sure how Gopnik came to believe the Duchamp urinals displayed in museums are all “visibly handcrafted replacements” but perhaps the more important point not mentioned comes from a 1961 lecture “A point which I want very much to establish that the choice of these “readymades” was never dictated by esthetic delectation. This choice was based on a reaction of visual indifference with at the same time a total absence of good or bad taste…in fact a total anesthesia” Surely Eva and Franco Mattes’ chip does a better job than even Duchamp with achieving that goal. Notably, having just spent a bunch of time in the Duchamp room in Philadelphia, it’s almost impossible to believe Duchamp used “total anesthesia” as an object selection criteria. If he did, he failed anyway.
