has anyone compared the DNA of the final generations to determine if they are genetically identical or radically different?

let's face it, any form of voice communication is open to room bugging -- the big point is how open the system is to remote and automated access. PSTN is not really foolproof but it did place a legal responsibility on the provider to keep the lines secure -- you knew who to sue. Upgrading PSTN to all-optical would suppress the vast majority of casual hacks. Are you prepared to loose all 'assurances' that the party called is actually there? Anyone care to comment on the stress created by this modern anonymity?
