64-bit integers suck rocks.
Here are some things for which they suck:
Times, in a *real* resolution (like, oh, say the resolution our
computers actually give us, for some processors *nanoseconds*)
Universal addressing, for which you essentially need: number of
network addresses in the world * number of bytes on a machine. The
width of an IPv6 address is six bytes. 64-bit integers would leave
only two bytes to address my data. Since I could easily have well
over a terabyte of storage at a reasonable cost, this is ludicrous.
Instead, we have six bytes of network address *plus* at least
another six bytes to index local storage.
