I had a similar thought recently actually, that consciousness is more than the brain. Is gt4 conscious? Eh, I don't believe anyone knows what that means but is it comparable to human consciousness? I don't think so, but how could it be? It senses words, so it knows words, so it speaks words.

I hear it said all the time that llm's don't really understand what they're talking about, but they seem to understand as well as they can given the dimensions they are aware of, using your terminology. I mean how can I describe anything myself without sensory details? It sounds like. It looks like. It feels like. It behaves like. We got all that knowledge by sensing, then infering. There's no special sauce that creates understanding from nothing.

I don't have any links but imo the experiences of people who were born without a sense, and especially those who were later able to gain it back, strongly supports this idea that something can only be conceptualized in the terms that it was sensed in.
