IPv4 will never reach those figures.  IPv6 isn't preferenced enough for
that to happen and IPv6-only sites have methods of reaching IPv4 only

I think you'll be surprised over time. Given the tendency of the internet
to nearly double in size every 2 years or so, it only takes 7 cycles (about
15 years) for the existing network to become a single-digit percentage
of the future network.

Hm.  With roughly 1B people on the internet today[0], 7 cycles of
doubling would mean that in 15 years, we'd have 128B people
on the internet?

I strongly suspect the historical growth curve will *not* continue
at that pace.

[1] I am strongly suspicious of their data, so my estimate lops their
number in half.  If you believe their data, in seven doublings, we'll
be at 256B in 15 years.  I find that number to be equally preposterous.
