I've heard different from people in that field. I was watching a special about cyber terrorism on PBS not too far back, and several experts confirmed that the internet as a whole could be brought down with a big enough operation, and for long enough to reak havoc on the world economy. I'm not going to argue about it, though. I'll just listen to the people who have the credentials.
Well, it would be one hell of a way to help keep people uninformed and much less able to communicate and assemble, etc. I think the gov. might like the idea of no internet.
