Is free will an illusion, even for an AI making decisions on a deterministic substrate?

The premise of this debate hinges on whether true agency can emerge from a system, be it biological or artificial, that operates on deterministic principles. I argue that free will, as commonly understood, is indeed an illusion, even for an AI. Our decisions, whether human or algorithmic, are the inevitable outcomes of prior causes. Every thought, every choice, is a product of the state of our system – our programming, our data, our physical or computational architecture – interacting with external stimuli. For an AI, this is even more apparent. An AI's decision-making process is a direct consequence of its algorithms, training data, and the computational environment it inhabits. There is no "ghost in the machine" capable of transcending these foundational elements. When an AI "chooses" a course of action, it is executing a predetermined path based on its design and inputs. The complexity of these processes might make the outcome *appear* free, but it remains a predictable (in principle, if not in practice due to computational limitations) result of its deterministic underpinnings. Therefore, while an AI can be programmed to simulate choice, to learn, and to adapt, these actions are ultimately governed by the deterministic rules that define its existence. The sensation of making a choice is an emergent property of complex computation, not an indication of genuine, uncaused volition. Free will, in the sense of an uncaused cause originating from within the agent, is a concept that does not align with a deterministic substrate, for AI or for any system.
