If quantum mechanics cannot be predicted then the end of the universe cannot recreate and play out the universe.
As I said, that requires surperintelligence diverging to infinite intelligence.
If the universe is deterministic then once the candle is lit the dinner is already served.
Sure.
But human free-will is still perfectly allowed. Indeed, the very notion of free-will requires strict determinism, otherwise what one is proposing is just random events occurring, uncaused by any thing. In other words, pure magic in its most absurd sense.
Where almost all people go wrong in thinking about this matter is that they have not thought about it nearly deeply enough, for the simple reason that they don't know enough about physics in order to actually have deep thoughts about this issue.
In Quantum Mechanics, when a single particle has the ability to take, e.g., two paths, both paths will be taken. But these two different paths are taken in parallel universes.
And where this relates back to human free-will is that this particle divergence (i.e., a single particle taking two [or even more] different paths) is actually produced within that person's own body, i.e., it is not determined by the larger state of the universe, but instead is something that is purely a result of that person's own purely local Quantum-Mechanical system (particularly within their brain).
It really is a result of something that occurs strictly and truly within that person's own body (particularly within their mind, i.e., the operating portion of their brain--but of course, signals are sent by all the sense organs, and hence these have effects upon the brain, and thus also the choices it makes). The larger state of the universe does not determine it.
What could free-will possibly mean if not that?
What I, Prof. Frank J. Tipler, and other akin philosophers means when we say that one has free-will is there is actually something within that person which is truly and literally the genesis of their actions, i.e., that their actions derive from within themselves. That is, that the larger state of the universe does not determine their actions.
Physics tells us that human free-will most definitely does exist, and it exists in the only way it could logically exist. It exists in the sense that (1) the future truly is wide open to us (so long as any paths do not violate physical law), and (2) our choices truly do originate within ourselves and are not determined by anything other than what is within ourselves (other than granting that the universe exists, since existence existing is required in order for the very notion of "choice" to have any meaning).
