human is undoubtedly making connections and associations far more complex and expressive, but at bottom it’s all just “sound = thing”, no? 🤔

The understanding of this complex and expressive structure is significant because it allows you to convey novel or abstract information. You will not be able to explain what a walk is to a dog without a demonstration, while you will be able to do so (to some degree) to the unfortunate hypothetical person who have never taken one before.
