You both speak about using the machine's ability to apply deterministic
rules, and apply them many times, to generate/identify the emergent
behavior of those rules. This can only be done by a machine because the
behavior can only be identified after a large number of iterations. If
a human programmer defines the simple rules, I doubt the programmer
should be credited for the emergent behavior.
The actions of a program that should be attributed to the program, and
not the programmer. In the simple cases this distinction is
unintuitive. The simple tools used in human history never needed a
language that could make distinction between the work done by the human,
and the work done by the tool. The increased complexity to do so would
make communication wrt simple tools verbose and inefficient. Consider
the phrase "I hammered a nail" to "I guided the hammer to hit a nail".
If a person sees the computer as only a simple tool, they will not make
the distinction between what the programmer does and the machine does.
They will not accept a more enriched form of English to make these
distinctions. And when an emergent behavior is identified, attribution
to the programmer is made, no matter how unexpected it may have been.
