I think virtual art presents a challenge. It can sometimes even be a menace that robs reality of all its meaning and of all its juice. But the best digital artists hate computers. I hate computers. I personally derive pleasure from destroying computers.
Computers are the first medium to have ideas built in.
You can say there's some theory involved with using a camera, but to find a machine that really has ideas built in, you have to go to the computer. By its nature, a computer has ideas built in because it has a program, which is, basically, ideas that have been frozen into it. When you use a specific music program the choice has been made for you. So, as soon as you start using it, you start nailing yourself down. In every other medium you want to understand the material and see what it wants to do.
