A program is a linear sequence of instructions that the machine
unfolds to perform the operations recorded therein.  A book is a
linear sequence of words that the mind unfolds into impression. A
state transitions to a state. I don't see much difference from the
drawing of symbols through silicon and metal to the brush of symbols
across the electrochemical mind. The symbols may carry great intent
and may be used to achieve effect, but the mechanical working of the
brushes is incidental to ideas.
