As the author says, you could argue both ways - either that the internet is a great tool with a net positive effect on people (those who know how to use it and can ignore the noise) or that we have adopted it so quickly and blindly that the internet hasn't caught up with humanity, causing these harmful side effects. Sometimes I think the internet was actually better 15 years ago, all things considered.
However if we expect it to become our sixth sense, we better a) evolve faster as a species to increase our bandwidth, and/or b) humanise the internet, educate ourselves to use it better, and consume information in a more natural way. Since the former is nowhere near, I'd like to see a Richard Hendricks appear and introduce Internet 2.0 for humans. But just like the author I don't know what that "better version" really means, or what it would look like...
