To a rabid base2 fanatic, the "10" in 2^10 is
repulsively decimal. What is it? 2^3 + 2 = 2^(2+1) + 2
or 

      2^(2^2^0 + 2^0) + 2^2^0

if you prefer.  Ugh.

Aren't there numerical notations that use a comma
to chunk digits 4 at a time?  And in the binary world we use 10?!

I would have thought that to a base2 fanatic, the "G"
should be 2^(2^5), ie. 4 decimal G's. 
(2^2 + 2^0)'s not so bad in the world of powers of 2.
