Anything done on a PC could be construed in this way.
Remember when people used ta write letters by hand?
Remember when people used to work out their own budgets?
Hell... Remember when people used used to handcode HTML? now you got Dreamweaver, Frontpage blah blah blah
The same can be said for any technological advance... i mean remember telegraphs, then landlines now mobiles... where does it end?
It can still be called art. Just because it was created on a PC does not exclude it as being art.
