I think the beauty of CG lies in its ease of use. That and the fact that just about anyone can sit down at their computer and have an image finished in a relatively short amount of time. Granted, it does take some level of skill to do the things that masters such as Hobbit, Beton and others can do, but for a beginning artist, I can think of no simpler way to break into the art world, even if their first attempts are little more than shiny spheres and a water plane. :)
