If using your hands is the criteria for art why not just pick your nose while you hit the print button on your computer.
I think art is a uniquely human endeavor. One thing that makes it more human is a person making it, not just a machine churning a product. Why do we visit art museums and galleries? Why some prefer to go to concerts while we have stereo systems? Yes there's are that uses technology like the work of Bill Viola that is delivered with a machine. But with work involving materials, art made by an artist is generally more valuable as a collector. There are various reasons for making and consuming art, but my reason for participating in the creation and consumption of art is for me transformative when I make it and when I see other people's art.
