Thoughts on "Digital Nation"

We've only watched a few segments of "Digital Nation", but from what I have seen, I've personally found it somewhat interesting. To be honest I have been a part of plenty of conversations in which the focus was technology "taking over." However, I have never seen any actual experimental studies done. What I personally found interesting is the idea of "less is more" when referring to brain activity. It was proven that people used more brain power to surf the internet than read a book. At first it may seem as a "pro" rather than a "con". But the doctor who performed the tests stated for correction that it was actually not a good thing.
It was interesting to hear that in surfing the internet, the average human is actually overloading their brain, because there is so much going on, therefore alot of brain power goes into making decisions, rather than being decisive. Reading a book is something that you choose to do, so the decision is made and you are just following through by reading. I would be interested in seeing if this idea is explored further in the coming segments of "Digital Nation"
