During History class the one thing that I've learned more than anything else is that nothing is infinite, and everything is constantly changing. Every generation thinks that its way is the way, and every time this is not true. So what do you think will change over the course of the next...oh, let's say 30 years. When the teens are parents and the parents are grandparents, and the non-existent specs are teens, what will we be leaving in? What social, economical and environmental changes do you expect? Basically, what will the world be like in X amount of years?
