Nah, must be quantum leaps in our ability to produce space-efficient
codes :-)  :-)  :-)  :-)  :-)

Sounds pretty scary.  Now, you'd never guess it from what appears
in comp.arch, but the chief use of cycles is pushing around 8 bit
unsigned quanitities that by convention stand for printable symbols
representing a curious code called the "alphabet".  So my challenge
to you (or anyone) is to tell me what your word processing would do
with 32+ addressing bits?  Ground rules: no Emacs jokes, can only
include the space costs of support tools when clearly part of the
word processing, and no credit for mere time advantages.  Well?
