You haven't really defined "program", yet.  Do you mean the ascii
code?  I can see how that could arise from a random source, but
doesn't it take a conscious being to look at the source code and
label it as a "program"?  I suppose it would be easy to design a
program that would randomly generate syntactically correct ascii C
code that would compile and run without run-time errors (probably has
been done).  But would you really call such a random product a
program?  And if so, what's so interesting about programs as such?

Good point.  But even if a program were accidentally generated
randomly (like the fabled monkeys accidentally producing a Shakespeare
play), would it not require a conscious being to *label* such a
production a "program", in order for it to be one?

I'm not sure about this point.  I suppose there might be an argument
for saying that the enterprise of science is to discover the programs
that exist in Nature, so that we can understand, predict, and control
Nature.  In particular, the DNA system could be (has been) described
as a program.  I'm not sure if this usage is legitimate, or if we are
engaging in a bit of anthropomorphizing, here.  Or "theomorphizing",
if we find ourselves thinking as if the universe was somehow
programmed by some sort of intelligent Being and we are discovering
what that program is.
