I have to admit my mouth is somewhat agape from this sort of tunnel vision.
While digital media will certainly continue to flourish, I disagree
that there is an 'aesthetic' that is specific to digital media. With
your argument intact, a guitarist who does nothing but release
digital files of their acoustic work exists outside of the 'digital
vacuum', but the aesthetic of the music doesn't change (perhaps in
some cases it might if we were arguing live vs. recorded).
I'm not so sure a discussion of aesthetics even includes the
presence of 1 & 0's or an analog signal.
