In fifteen years we will have the hitch hikers guide to the galaxy: an electronic book sized machine that can make phone calls (complete with live video), take notes, quickly and easily provide information, perhaps project movies (in holographic form?), etc. Colonization of Mars, hover cars, no fossil fuel, downloadable drugs (virtual reality environment), commercial space travel, and some type of new closeness with machines, whether it be through actually installing microchips or ports into humans, or through enhancing physical human aspects. Certainly virtual reality will be a large part of our realities.
American Idol winners become global emperor for the week, and decide on the distribution of rationing out coca cola and super antibiotics to the world. Mars is cut off, poor bastards, there's just not enough cola to go round. Cola is also no longer sweetened with the extinct plant sugarcane. All sweetener is artificial. Human experiments on mutating the dolphin brain have forced the dolphin to evolve, making it the smartest being on Earth. The dolphins teach humans to breathe underwater (like we did in the womb), and all mankind begins to make the move into the ocean. Surfing takes over soccer as the world's most beloved sport, sharks are butchered into extinction.
On a side note, I really have no idea what the future holds. I am pretty adverse to technology, and don't take in much news. I'm an introverted artist, I can only really tell you what I might be like in the future, and even that will probably prove to be inaccurate.
