I'm seeing a lot of "bah, humbug" responses to this article, especially regarding the subject of concentration/learning/etc., but i think that it's quite possible that this shift in paradigms of communication has a broader reach than we are currently considering.
If more people are more connected, doesn't this mean that there will be more collaborative projects? maybe the "hive mind" will replace a lot of the expertise we currently value?
As a teacher, i am especially interested to see how this interconnectedness affects learning and schooling. It's conceivable that in 30 years, we won't be teaching the knowledge via memorization of facts, but instead teaching the knowledge of where to go to look/who to talk to in order to obtain those facts.
Will this affect how people assemble bits of information? sure, but maybe the collective mind can produce something as good as, or better than what one person can construct on their own...
maybe it's a load of hooey, but as a teacher i can't afford to not think about these things
