Whither original art?

Until recently original paintings reigned supreme in the viewer's mind, and for very good reasons: in an original colors are truer and often more vivid;  one is most sensitive to the textures; the frame and settings generally add "depth" to the experience; perhaps most of all, the proximity to the actual object makes us feel greater physical, even temporal, proximity to the painter.  All told, the experience is more "authentic" than the experience of secondhand viewing, via prints, magazines, or the computer.  

Digital art erodes  the supremacy of the original art. A digital artwork  can be available in exactly the same way to all viewers. including the originator, the digital artist.  If the artist so desires, she could even bring the viewer into the process of creation, making that part of the viewing experience.  Examples already exist of this on the net.  

We are told that the future will bring us a gadget at home that can quite literally re-create a work of art on the spot, in our homes, perhaps to our specifications,  by, say,  changing the color scheme so that it better matches the sofa.

Consider how that would change the nature of original art!  Even if the art were not digital in the first place, such a gadget could reproduce it even as scanners already can.  What is the difference between an original photo and the copy?  

The mind boggles.
