Was the setting in "The Lateness of the Hour" a post-apolcalyptic one?

The episode confines itself largely to the Loren's mansion, with a storm raging outside (symbolic, perhaps, of the turmoil humankind finds itself in the throes of). And when it does reference the outside world it's usually in a somewhat wistful manner like humankind has seen to making Earth a shell of what it once was. This leads me to believe that maybe the world Dr. Loren and his family live in is not unlike the world of, say, Mad Max, and Dr. Loren, through his genius and wealth, has found a way to insulate himself and his family from its unravelling.
