There is one motivating factor that carries throughout history and drives everyone to pursue being modern and it is simply being
BETTER THAN EVERYONE ELSE !!!!!
The drive for modern is fueled by the drive to always have the newest shiny toy. At the begening of the 20th century came a time of reform in design where the movement changed the OLD to NEW.
Something that is always changing and it seams like a new version come out evey other day is technology. I remember when my moms cell phone was a brick and had extreamly limited ablities and now we have iPhones that are basically small computers that can control pretty much everything we want it to.
