Those buildings were crafted by artisans that are few and far between, these days. Though, I suppose that it would be possible, at some point, if not now, to use 3D printers to bypass the human aspect of the artistic intricacy that is involved in such architecture. The question is: Do many developers and architects really want to revisit bygone architectural/design trends such as, Art Deco?Of course we can. We haven't suddenly forgotten how to do it. The issue is won't not can't.
