I am not. I want to understand what is the difference between “feeling” as result of electrochemical reactions in our brain and “feeling” as result of math performed on a numerical matrix. I am perfectly aware those are not the same, but the result may be similar, and what we care of the result determines the conclusions we can make.

You need to clearly explain what is thinking and what in the “thinking” process of LLM is not thinking. If you define “thinking” as electromechanical reactions in human brains then LLM is not thinking, but it is not a useful definition.
