Spending time among the replicators has helped me become aware of what it’s easy to acknowledge intellectually but more difficult to feel: that a piece of art is mortal; that it is the work of many hands, only some of which are coeval with the artist; that time is the medium of media; that one person’s damage is another’s patina; that the present’s notion of its past and future are changeable fictions; that a museum is at sea.
