48 bytes is a bigger address space than (I think) would be necessary
for many generations to come...

according to this estimate:

There are about 6 x 10^77 atoms in the visible universe (meaning the
part that came from the big bang). Other google searches brought
results within 20 orders of magnitude of this. So, 

256^48 > (10^2)^48 = 10^96 > 6 x 10^77

Reading through the inequality we get:

256^48 > 6 x 10^77

and I assume that we will not need to adress every atom any time soon.
