To clarify the metaphor: I’m looking at the nervous system as the layer that handles proprioception and reflexes. Right now, AI has a 'brain' but it doesn't know where its 'limbs' (tools/APIs) are, or what the 'pain' of a security violation feels like.
We want the AI to stay blissfully emotionless, but we want the infrastructure to have the 'reflex' to pull back a hand before it touches a hot stove (like a database it shouldn't be wiping).
