I still don't quite get it myself and wouldn't buy one, but I guess its hard to speculate how the market will react.
What? It doesn't to me, actually. Modern schooling and news media give us many of nifty tools, but also do damage to our education and ability to think independently, and so in turn to society. So, I'm not sure I agree we can dismiss debate like this. I pick this quote because it's an example of why this is a poor argument.
The whole argument the author uses assumes we have consistently progressed using media and surpassed the problems media critics pointed out, therefore critics in the past are wrong. Maybe it's true that they are always rather negative and forget the positive aspects of change, but there have been a huge range of critics with lots of criticisms that seem to have manifested true. Sorry, but you can't throw out an argument like this author did in a 1-page article, he just has too many presumptions for too complex an issue.
