I don't have much to add that hasn't been said, but I think it's just a case of shifting markets (and I don't mean that in a purely economical sense) - the cultural significance of silver gelatin printing (and traditional color) has already shifted. Where once the art world might have still unconsciously linked them to the world of advertising and commercial/editorial work, that can't be said anymore.

Anyone, these days, could throw together a 'book' with InDesign, or fake traditional printmaking processes - but I can still find thousands of people producing artists' books by hand and any number of print shops still using the old ways.
