Some writers have such a simple way of putting things that they can't be ignored.
An interview with David D. Clark, senior research scientist at MIT's Advanced Network Architecture group, "The Internet Is Broken," talks about reaching the law of diminishing returns in attempting to shore up the current Internet against the continuing onslaught of spam, viruses, spyware and coordinated attacks involving unwittingly recruited end-user systems. Dr. Clark is one of a growing number of computer scientists who would like to see a new Internet built from scratch.
There is already a project underway for replacing IPv4 with IPv6, growing the number of Internet addresses by several orders of magnitude. Today, IP addresses are either briefly on loan or expensive to lease. With all the new addresses, there would be numerous opportunities for augmenting existing protocols with built-in security features, like knowing exactly where an email message came from. That would put an end to a lot of tomfoolery out there.
