This is some sort of urban legend. If a routeable prefix was given
to
every human, using a predicted world population of 11 billion, we
would
consume about 0.004% of the total IPv6 address space.
....that's what they said about never needing more than 640kb of memory in a
computer......
we'll never need more than that!

Seriously,
As was pointed out recently, IPV6 will croak much sooner than it needs
to
for the simple reason that we structure routing intelligence into the
address assignment.

(The actual calculation is 11*10^9/2^48 since there are 48
bits in an IPv6 routing prefix. Or
11,000,000,000 / 281,474,976,710,656 = 0.000039 )
