Please disreagrd this message! I'm really sleepy....I missed the
fact that a 128-bit processor would access over 4 billion times the
amount a 32 bit one would. I forgot all about the 64-bit ones. In this
case, I would agree, and go as far as to say that humanity will _never
access 300 tredecillion bytes, since to do so would require us to
dissassemble several planets. This had been discussed when I wasn't
paying attention...
