As social organisms, the sociocultural context (great term, don't you think?) in which a human brain lives and develops is an important factor determining what gets sensed, what gets connected, and what gets pruned. Sociocultural context is just a fancy term for the society in which we live. Information technology is one of the features that defines the sociocultural context. 

Scientists who study these things are in agreement that the sociocultural context in which a human brain experiences youth through adolescence has a permanent affect on that development of the brain. These lessons learned during this time become what is expected. (This is no surprise-- all generations mourn and decry the loss of the culture they experienced as adolescents.)

Throughout human history, there is evidence of one dominant information technology being replaced by another. These transitions have been noted for significant changes such as the introduction of writing, and the introduction of writing to the masses through print, and then various electronic technologies. At each transition, there is also evidence of turmoil within the culture. At each transition, there is also evidence of unintended consequences and unimagined interactions between technologies. 

One of the reasons for all of this turmoil is that the skill and knowledge that has value within the context of one dominant information technology is usually not transferable to the context dominated by the next dominant information technology. 

The Shift Happens videos have been around for years, and still give a good illustration of the changes in our culture (like 'em or not):
