This does, of course, assume that the population remains earthbound =

I think that is not entirely likely.

Yes... The technical considerations should override silly efforts to =
keep more than 99.99% of all IPv6 space in reserve
for some unprojected need since we have real projected needs for the =
0.001% now.
