White Christmas spoiler question...
In the last scene, the COOKIE of Joe is trapped in the pod for eternity, correct? The actual Joe still exists. This was established in the second segment with Greta, where her cookie becomes her slave, basically.
Thus, Joe is not the one suffering in the "pod," but rather his digital copy. So, being that Joe expressed disgust with Matt, for creating the copy of Greta, and making her a prisoner, is part of "real" Joe's punishment, knowing that his digital copy is suffering - or does he even know?
