Perhaps things have slowed down for us here in the developed, western world, but I have heard of an amazing shift in the third world; cell phones.
For example, in Kenya there are 37 million people. Of those, only 1.3 have electricity. No lights, no fans, no TV, no electricity at all. However, 17 million people use cell phones and the number is screaming upwards every day! Imagine what a fundamental change it is to be able to talk with anyone at a distance in a developing nation? So much of what we take for granted in the western world boils down to the ability to pick up a phone and ask for what you want, be it goods or information.
The article I lifted these figures from was discussing a solar powered cell phone, which will cut the final cord from the main grid. Now people who cannot walk to a grid connected location can still call for help, call to find a job, call to talk with a distant loved one.
In the book Guns, Germs, and Steel http://en.wikipedia.org/wiki/Guns,_Germs,_and_Steel it was postulated that the rise of the main Eurasian regions in history was mainly due to the free travel of ideas across a broad band of land where climatological and geological conditions were mostly similar, thus allowing different ideas about agriculture, living, and warfare to flow back and forth easily. This mixing of ideas is what made the Eurasian continent most often dominant over the Americas and the African continents, which are spread out longitudinally and thus cover a wider spread of terrain conditions and weather conditions.
The advent of the mobile phone will become an equalizing factor, ideas will be able to spread faster and faster among the populations of the South American and African regions and the quality of life there will begin to experience the same kind of rapid upward swell which we in the western world assume is our birthright.
