Hi,

here is the trade off, do we complexify physical (hardware) = CISC or
do we complexify information (software) = RISC...

http://webopedia.internet.com/TERM/R/RISC.html

               "There is still considerable controversy among experts
about
               the ultimate value of RISC architectures. Its
proponents argue
               that RISC machines are both cheaper and faster, and are

               therefore the machines of the future. Skeptics note
that by
               making the hardware simpler, RISC architectures put a
greater
               burden on the software. They argue that this is not
worth the
               trouble because conventional microprocessors are
becoming
               increasingly fast and cheap anyway.

               To some extent, the argument is becoming moot because
               CISC and RISC implementations are becoming more and
               more alike. Many of today's RISC chips support as many
               instructions as yesterday's CISC chips. And today's
CISC
               chips use many techniques formerly associated with RISC

               chips."

    The ideas here can be categorized using Pratt's "Stone Gamut"!
