certificate chain validation flaws exist in Internet Explorer, Mozilla, and other browsers that enable anyone to forge any server certificate.

I would say that certificate-based server authentication is dead, except that it is still produces huge annual revenues for the companies that sell this useless snake oil remedy for a problem that doesn't exist.

Nobody has trouble communicating their public key to the people who need to know what it is. Certificate chains presumed that this would be impossible in an overly-complicated anonymous commerce model across geographical and political boundaries in the borderless nirvana of cyberspace. Faulty presumption. End of technology? No, unfortunately not.

The tax man must be paid else the padlock will not appear. Certificates are a means of extracting money from people who want to do something meaningful with the Web. They are not a security countermeasure. Thus proof that they don't work doesn't cause them to go away... It just reveals their true purpose.
