Although a cute example, it does have a corollary in the computer chess world
after all. It is called computer resources. If I have a faster processor, I have
more fertilizer. If I have more memory, I have more water. When I run the same
program with the same position on a different computer, I am running it in a
different garden with different characteristics. Hence, your statement (or
argument as you called it) does not really hold. We call these "techniques"
resources. Therefore, you need not argue with yourself and can feel more
confident that the other statements that you made may contain more validity
since a reduction in resources should not be considered pruning.
