IPv6 is no more difficult to understand than IPv4. In many ways it is easier since there are fewer legacy RFCs pertaining to it. System administrators don't understand it because they have not been forced to learn about it yet the same way they were forced to learn about IPv4. Backwards compatibility would have made it far more complex. If you sit down to look at IPv6 it's really quite straightforward. I think a lot of network admins are secretly hoping to retire before they have to learn a new technology though.
