Consciousness is substrate independent, but that's not the differentiator here:

My toddler son is conscious, he feels happiness and sadness and have urges and impulses without needing to know the entire history worth of writing from human civilization.

A dictionary is not, and a LLM sized dictionary with optimized query is still not conscious.

It doesn't have anything to do whether consciousness is substrate independent, or even analog vs discrete, the overall implementation just aren't parallel.
