Technology does drive history, and will probably continue to do so...but to who's advantage?

In Merrit Roe Smith's article "Does Technology Drive History?" some very interesting points were brought up. The one painting titled "American Progress" that Roe discussed represents America moving into a great and successful future with technology, and leaving behind those who are not apart of this technological journey, nature and the Native Americans. So if we jump foward 150 years to current times, which groups are the new Native Americans? We are a nation of immeadiacy, we always need the next new technology, whether it's the new i phone, i pod, etc; technology is still driving our nation and our lives, and it's expensive. Not everyone in the United States are middle to upper class, and as the technologies become more involved in our everyday life, people who cannot afford these things are getting left behind. There are going to be less oppurtunites for the lower classes because they are not going to understand the technologies that are driving our world, and thus the jobs within it. I'm afraid to wonder what the world will be like in twenty years; how much further will technology have advanced, what kind of jobs will be availible, and how will people react to it?
