"at least to rhyme" is very specifically a metaphor in that it does not require systemic logical matching... I don't literally require rhyming or a logical system that is comparable. It's also utterly useless for _system thinking_, which is the author's subject matter, precisely because it is at best loosely related. An analogy, or analog, is a much deeper match in that means to transfer the understanding and knowledge of an existing system to a new target system that closely parallels that understanding and knowledge. Analog computing was literally "creating a model of the problem" that closely matched the real problem. Agreed that metaphors are not inherently bad, but the dependence on metaphors rather than analogies is symptomatic of a lack of depth in understanding when attempting to convey knowledge.
