Then Determinism has to be the case. "Materials" or "physics" are not conscious, intelligent, volitional entities. Human beings then become nothing but the byproduct of impersonal forces.
But it does. In fact, it absolutely necessitates Determinism.Re "appealing to quantum fluctuations etc." the point there is SOLELY that the standard view in the sciences doesn't support that determinism is the case.
All an appeal to quantum fluctuations adds to the situation is that we can no longer KNOW what impersonal forces are creating the illusion of personal volition; it doesn't mean that personal volition is anything more than a rather odd, inexplicable and causally-irrelevant byproduct of the determining quantum forces. Human choice is still not real.
The quantum strategy thus may confuse the thinker, especially if he mistakes his own no longer knowing for some sort of denial of the facts, of Determinism; but that actually does not change the equation when it comes to Determinism.
As the video points out, there's still no causally-relevant place for consciousness, identity, choice and the human in such a universe. Indeed, it's arguably a WORSE universe for volition than the old Materialist/Physicalist one.
