I am a soldier and language is vital in every day of my job. Tone, word choice, cadence ... all of it conveys meaning in a way that an LLM simply cannot. Soldiers will not follow an AI up a hill, nor will they follow those they know use AI to pretend they understand a subject.
Want to sound smart? Watch blackadder. Want to win no-win aguements through wit? Watch Archer. Want to inspire your troops to do somthing unpleasant? read and watch shakespeare. An LLM can teach you nothing that really counts.
