It's a convenient metaphor. The second thing about this Language Model guide is that it goes beyond language. Or rather, beyond 'language', as it derives from the Latin lingua , tongue, 'that is spoken' . In NLP terms language is an external surface structure mode of expression far removed from our internal deep structure sensory processing and even further removed from our internal emotional responses to reality. But if we resurrect a 17th century alternative meaning of language as 'a means of expression otherwise than by words' and add this to the original we can usefully deepen the meaning.
Language then becomes 'a means of expression and communication' .
We even pace ticks and giggles. An obvious use, though by no means the only one, is in psychotherapy. As the client discovers information about a troublesome pattern underlying their present state, the information feeds back into the system and self-correcting change occurs. The pattern will not perpetuate. Sometimes the metaphor transforms completely, and the problem state with it.
