Name literally any other technology that works this way.
> Guide dogs, sniffer dogs, falconry...
Guide dogs are an imperfect solution to an actual problem: the inability for people to see. And dogs respond to training far more reliably than LLMs respond to prompts.
Sniffer dogs are at least in part bullshit and have been shown in many studies to respond to the subtle cues of their handlers far more reliably than anything they actually smell. And the best of part of them is they also (completely outside their own control mind you) ruin lives when falsely detecting drugs on cars that look a way the officer handling them thinks means they have drugs inside.
And falconry is a hobby.
