what is the life expectancy of IPv6?  It won't live forever and we
can't reasonably expect it too.  I understand we don't want run out of
addresses in the next 10-40 years but what about 100? 200? 300?

We will run out and our decedents will go through re-numbering again.
The question becomes what is the life expectancy of IPv6 and does the
allocation plan make a reasonable attempt to run out of addresses
around the end of the expected life of IPv6.
