Your observation reminds me of this book, Simulcra and Simulation

The very brief (and bastardised) summary is that we're cutting ourselves from what is real, so we base our art on the fake reality that we're experiencing.
I'll never forget when one of my teachers asked: "who has seen a sheep?" The entire class put up their hand. The next question was "who has seen a live sheep, in front of them?" more than half the class put their hand down. We all know what a sheep looks like, but not because we've been near one.
