In the year Twenty-One-Twelve

What could possibly happen in between now and 2112? The answer is a lot of things. Most of the things I have in mind are various ways that humanity could be wiped out. Who knows, maybe there will be a huge earthquake thanks to shifting of platonic plates or whatever they're called which will trigger a giant tsunami that destroys everything not destroyed by the earthquake. Perhaps we'll all go up in smoke thanks to global warming. Or maybe we'll just all drown. Maybe we might get hit by a meteor comparable to that which ended the age of dinosaurs, and die a slow death thanks to lack of sunlight. Maybe there will be new airborne diseases that spread quickly enough to kill everyone on the planet, or maybe we'll just have a good old-fashioned nuclear explosion. However, since none of these options really involve people surviving, I'll assume that humanity persists on for another century. What they'll do at that time is just as hard to predict as the winner of the Super Bowl three years from now, but I would wager that technology will have advanced far enough to create possible worldwide communication. Perhaps something like the holographic projectors used in movies could substitute for a person's presence, like if they're ill, for example. This could also cut down on absences, as the people who would otherwise have been unavailable are there, albeit within spirit.
