where in that reply did i ever say “how free will works”?
what you’re admitting here is that there’s ultimately no free will, no real decision-making, just the inevitable outcome of physical laws acting on matter.
i don’t know why you’re still trying to grasp at the language of free will or pretending you actually have it in your worldview. you’ve already collapsed the self into a deterministic system.
you've defined this system as "you" for simplicity of language to make communication in your worldview more coherent, but it's an illusion. there is no you, there is no true self, and there is no true free will.
to go with your scifi scenario, if there was a sufficiently complex computer that could know everything about you and your environment down to the most tiny detail, it could predict every possible thing "you" will do / say / think / feel. There is no real choice, there is no good or bad, there just is.
Your language is restricting you from grasping reality. You say there is no real me/self and its an illusion while that is not true because if it was an illusion there would have to be a reality that this illusion is mimicing. What we have is THE reality, this is what consciousness is. A very complex mixture of reacting things. The scale of the possible determinism you refer to is way to complex to act like it means free will isnt "real" whatever that means in this context.
Also as I stated in an earlier post, quantum mechanics which are - from todays scientific stance of knowledge - REALLY random. This mixed in randomness probably creates an unpredictable mixture that we might know as free will.
In the end, I stand by my point, which is that the christian god is a nonsensical self-contradicting pile of bs.
