Digitalizing is a way to translate reality into bits. Digitalized reality isn't reality. It's a semplification, focusing on particular aspects. The digitalized model is mathematical, so perfect. Digital art, no matter what you want to describe, is a limitation of men's possibility of expression, becuause it limits your brain on digitally building structures wich your artist's brain, analogic, can imagine and realize by hand in a short matter of time.
Software is another great limit of expression.
I'm an engeneering student, son of an artist, and I catch the difference, believe me.
