Mind is an emergent property of the brain. When a brain operates, you get mind. How can it be mindless?
While the emergent property we call mind is a property of the brain, the processes that lead to outcomes are completely dependent upon conditions that we do not choose (because we can't, because there is no we). In Autodidactism, what we call 'mind' is the emergent outcome - the process itself is mindless.
You keep talking about a "we" as if it was separate from the body. The neurons firing is US. That's us making a choice. There is no other "we" to control it.
Sigh. I feel like we are just talking past each other at this point. Because I need to keep using some kind of term to denote whatever it is that is our self, it seems like I am separating out the I. When I am looking at the situation from the perspective of Autodidactism, I am assuming that "I/we/us/you" equates only with the physical components of our body/brain. I am following your line of reasoning, as I understand it, that we are the result of a biological process, nothing more. What emerges from that biological process we call mind and choice and will and our personality, likes, dislikes, etc.
But, if it is a cause and effect process then there is no place where the course of events can be altered. There is no place where choice can occur,
no mover to make that different choice. See, by saying "no mover" I am acknowledging your position that there is no other us, or unseen or magical bits.
I'm not sure if you missed my question about the computer analogy. If you put all the same data into the same computer with the same wiring, does the computer choose what output it gives you?
If the wiring changed every time you entered data, then it would quickly become too complex to predict the outcomes, but still, if you knew the wiring, you could predict the outcome. In that case does the computer choose what output it gives you?
Can you think of any computer, AI, Turing machine that could choose what output to give you? What would have to be different?
