WTF: IPv6 in the Science journals?

Here's an example.

An entire generation of computer scientists has been born, educated, and gone to work since IPv6 was first invented.  There are very damned few deployments of it outside of the backbone.  The benefits are clear, but so are the implementation challenges.

The linked article refers to a government mandate for IPv6 upgrading.  I'd get excited about that except that I remember the first such mandate (around 1995), the second (around 2000), and the third (around 2005) – none of which had much impact so far as I can tell.  Outside of the squandering of vast amounts of taxpayer dollars, of course.

Sheesh.
