The demise of Britannica is being pontificated but I agree that it wasn't Wikipedia that killed it. I don't totally agree with this author in that the PC killed Britannica because it became our information portal through the Internet.
I always tell my students when they travel with me never to joke in airports about anything. I have to admit that the new NSA center with the best decryption capabilities in the world and a seemingly blank check will have me add this article to our reading list as we talk about privacy.

This particular issue is a black box so the article may be filled with conjecture. I thought it was worth the read,
