In 2014, we can readily extrapolate a post-apocalyptic future whereinn tribalism is all that's left of civilization. Separate tribes, huddled in fear, lashing out at anything different or new, the person with the biggest cache of guns dictating what is defined as strength, and what is seen as weakness.
Perhaps, even at some point, desperate humans will launch nukes in a last-ditch effort to prove their "strength" in the face of an ape culture on the rise, thus creating the Forbidden Zone. Who knows? A clever writer can square the circle in any number of ways and get us right back to Chuck Heston paddling for shore on that picturesque dead lake.
