Is the Internet so broken that it needs to be replaced, not fixed? A pretty alarmist - and very short - article in the New York Times suggests so. It's a pretty conventional diatribe against the current security arrangements and trust models on the Internet - with an emphasis on what anonymity implies for security.
The problem with "sky is falling" articles like this is that 1) there's no rational model for replacing the current Internet, only evolving it; and 2) even if you could build version two, who and what would move to the "New Internet?" In fact, there's a much more fundamental problem for the replacement of the current Internet and that is the depth and extent of the current Internet's infrastructure. The financial and technical underpinning of the current Internet makes a "lift and shift" approach to a new Internet impossible.
