And that the only reason we think AIs can just be brains in jars is because many of the people developing them consider themselves as simply brains in jars.
> Do they know what a hot shower feels like? They can describe it. But do they actually know? Have they experienced it
Is directly a knowledge argument
Also, it is an argument against physicalism, which I have no interest in debating. While it's tangentially related, my point is not for/against physicalism.
My argument is about modern AI and it's ability to learn. If we put touch sensors, eyes, nose, a mechanism to collect physical data (legs) and even sex organs on an AI system, then it is more generally intelligent than before. It will have learned in a better fashion what a hot shower feels like and will be smarter for it.
I really disagree. Your entire point is about physicalism. If physicalism is true than an AI does not necessarily learn in a better fashion what a hot shower feels like by being embodied. In a physicalist world it is conceivable to experience that synthetically.
