This Technology Review essay by John Hockenberry goes a long way toward explaining why you will never be too well informed if you only watch television network news.
Ironically, the editors of Technology Review magazine should see a reflection of themselves in this article. Technology Review used to have stimulating articles at the forefront of scientific research. Now they seem to have dumbed the magazine down to puff pieces on corporate technology development.
Thanks to lurker, Richard H, for encouraging me to finish reading the essay.
