The Passenger. Attack on Free Will. How AI Weaponises your Survival Instincts

If we look at all levels of from the quantum to the biological, to the social, psychological, natural, all the physical and space sciences  from the point of view of 'causal mechanics' or 'functionalism, can free will emerge from the recognition and understanding of one field? Or would the choices one makes from that position of understanding not be free will because the choices made would themselves be constrained by the limits of the conditions? And if those limits are recognised and the person attempts to push, explore ways to go beyond the rules governing the system, then is that attempt to expand, or gho beyond, the only sign of free will. Or is that also constrained within the mechanism. If a person was able to map out every cause of their current mood, would that knowledge make that person more in control or simply like a spectator of their life. And would either of those positions put the person in a mode of conscious awareness unaffected by what was being observed?
