The author also claims that a function (R^n)^c -> (R^n)^c is dramatically different to the human experience of consciousness. Yet the author's text I am reading, and any information they can communicate to me, exists entirely in (R^n)^c.
LLMs: (R^n)^c -> (R^n)^c
Humans: [set of potentially many and complicated inputs that we effectively do not understand at all] -> (R^n)^c
The point is that the model of how consciousness works is unknown. Thus the author would not present such a model, it is the point.
