I think in the future this stats will be more and more scary. Because people learn since the childhood to be dependent of that kind access to information and socialization using the tools that smartphone have to offer. Theres no away that people will stop depending of that technology, by the contrary, we need to do everything as fast as possible in your day-to-day life, and smarthphone will evolve to provide this needs.
Of course in the world there are many things that people don't have acess. But we cannot compare to smarthphone, they don't are guilty for the poverty that we see in the world. And, for some cultures, to have a smartphone and to depend of it is more important than other basic things.
By the away i try every day to use less the smartphone. Just because i don't know how to filter the good and the poor information that we have in internet. Most of the time i end to lose in facebook and i really wasting my time with a lot of bad information.
By the away, good post and info. I liked the subject.
