Sociologists have long tracked the relationship between technology and society. Each new method of communication and transportation changes the way society as a whole behaves.
It makes for a fascinating study all of its own. For example, organized religion didn’t spread on a large scale until the invention of the printing press, for instance, because that made it possible to mass-produce scriptures which could be taken by missionaries to other countries. For another example, the concept of a globally-traded stock market didn’t emerge until the invention of the transcontinental telegraph, with which information could be transmitted while it was still useful.
Technology improvements sometimes come at a price for society, as well. In our modern age, all of the improvements in communications and transportation has resulted in a speeding-up of lifestyle. We do so much more in a day than people 100 years ago could do in a week, and so it is expected of us that we keep that pace up indefinitely. For today’s young adult single is too busy wrapping up their education, establishing their career, and settling into their own lifestyle away from their parents to give much thought to socializing.
