I would argue that it’s actually the “frozen” nature of these digital spaces that marks the passage of time; we can see — very clearly in many cases — the point at which they stopped changing and were marked by what is now our past. If a ruined physical space is a memento mori, abandoned digital space is more like a time capsule: a place in which the future has simply never happened. These spaces are atemporal, then, in that they give us a vivid glimpse of our own past that we can experience in the present and perhaps extrapolate forward into an imagined future — but because they aren’t ruined, we don’t imagine that future in the same way.
