Another thing to consider is that art will always be at least somewhat dependent on technology. What you can do is inherently limited by what you have. If you don't have marbel and chisel, you don't have the classic sculptures. If you don't have paint and easel, well you are very limited to what you can paint. Even the quality of the paints, brushes and other materials are all different than they were a hundred years ago.
And technology only continues to advance at a greater pace, especially in other fields of art.
Look at photography. I can't help but find it ridiculous how much a "traditional" photographer will rack his brain over a little white dot in the middle of a black are. Just pop that sucker into photoshop and fix it!
Even amongst digital artists-- I've gotten a negative comment here or there because I like to use filters (especially the water color filter), and also make full use of whatever tools I know how to use. "It's cheating". To me, this seems ridiculous to me though. To some cave man with berry dies in era whatever, Michelangelo would be cheating with oil paint. Art evolves with the tools-- if you don't make full use of the tools available, someone else will. What matters is the final product.
Art is destined to change with technology, and new technologies will always be born with new arts.
My favorite art? Planted Aquarium Design.
This is an aquarium I designed 4 years ago. I really like it. Fact of the matter is, it wouldn't exist without:
-High powered florescent light
-Pressurized CO2
-CO2 delivery system including diffuser
-Filtration system
-substrate system
-fertilizers
and on, and on and on. You can't have tropical plants and fish from all over the world in your aquarium, unless you have planes, delivery systems, and aquarium industry to bring you the goods.
Point being, this type of art could simply not be done 50 years ago. Art is, to a degree shaped by available technology. If the average person had the same tools at his disposal as Pixar, art would change drastically still.
There's no point in thinking that this is anything new-- art has always continued to change, and continued to evolve along side of and be shaped by technology.
