While I agree with your general thesis, most of the time people don't want to or need "Art" from their music, books or paintings. They need something easy and exciting to read on a plane, or some pleasant 'noise' to have on in the background, or something pretty to hang on their wall that works with their room. Computers can probably soon fill all these needs and drive a lot of the people who produce these things out of work, without ever having to encroach on the realm of "Art".
