Because it has been kneecapped to prevent it.
Make the training network larger, force physical constraints on it (interesting paper in Nature Machine Intelligence recently showed remarkable likeness between brain regions and an LLM network given physical constraints), give it constant input and give it a reward model to optimise towards (ours seem to be feeling full, warm, procreating, avoiding pain and comfortable touch) and I’m pretty sure an LLM would start acting very very calculated very soon.
