Aesthetics isn't only a surface, an Image, a branding, but it's also an atmosphere in which experience happens. You could state, that the fictional world dominates the real world. You can see this in economy where e.g. advertisement and materials shapes a view on products and their value (and also politics). Since art is not created in a vacuum, the reception changes over time. That creates the problem, that the meaning of an art piece is not always sustainable in the intended way.
Also, art is reproducible through severely processes, especially digital art, which can be reproduced without loss in quality. An interesting question is: How can we create digital art and their available aesthetics, and therefore is easily reproduced but has a sustainable economic and ecological value?
