Control
They make an argument in the chapter that technology is an extension of human exploration. A sort of Manifest Destiny of the brain. I would tend to agree with this philosophy as i feel that the means and which we communicate have been evolving since the beginning of man. Anyway we can improve this communication we should take full advantage of. For example, me writing in this blog. As long as we can differentiate the good from the bad technology we can harness the goodness for some time. However, instances like text messaging are starting to detract from the demeanor in the way we communicate. A phone call is way more personal when dealing with people.
