If we were to give a /48 to every human on the face of the planet, we
would use about .000025 of the total available IPv6 address space.

You are to be commended for your leadership in conserving space.  Our
children will surely be grateful that thanks to your efforts they have
99.99999% of IPv6 space left to work with rather than the paltry
99.9975% that might have been their inheritance were it not for your
efforts.  Bravo!
