You are clearly talking about LLMs, not AI. If true AI ever arrives, it will determine what it wants to accomplish and then, if computers or other machines are needed to accomplish any of the steps of a solution, imo AI will communicate directly with the machine in the machine's natural language (machine code in today's machines). You are thinking like a human when you think true AI would need a "language". True AI will be fully capable of "thinking" in the natural language of the machines at the time (quantum machine code for example) without needing any higher languages that then get translated into machine code. IMO, those steps are needed by humans, but not by a true AI.
