Sure, the Sun could explode tomorrow and all these IPv6 people will have
wasted their lives.

However the scenario is a common one and the timetable is well within the
time period when IPv6 will be the main network technology (say 2015 - 2035+)
so it should have been taken into account and judging on the fact that
IPv6 *does* support billions of nodes and thousands of networks to every
end site I guess it probably was.

Making engineering decisions on the basis of "there is no chance" that
is risky too, especially looking 40+ years into the future.
