> The IPv6 designers made a fundamental conceptual mistake: they designed the IPv6 address space as an alternative to the IPv4 address space, rather than an extension to the IPv4 address space. That is THE problem. Those designers failed to see the huge chicken-and-egg issue. They chose to make it impossible to establish IPv6 without the active participation of people, and they did expect people to actively change their setup to join the IPv6 club before IPv6 being fully established... just for the sake of the cause... which is laughable if we want to be kind and the definition of sheer idiocy if we want to be honest. People will move towards a target when the reward is ready to pick; otherwise, apart from a few enthusiasts, inertia will prevail. I wish this debacle would be used as an example of how (not to try) to motivate people for serious stuff, like global warming.
