The definition of "free" and "will" are to shady to be scientific.
So there is no scientific arguing about it, just philosophical.
I like this take, but it also makes me feel like I could do a better job describing the intent of my question in more scientific terms. I hope to do so, here.
If one were to have sufficiently advanced technology akin to future MRI machines that could image the state of the human brain at Planck time resolution, my argument is that the very process of "a decision" (act, choice, idea, etc.) could be quantified. And if that is the case, then there must be chemical triggers and causal events that could have predicted that state of the matter and energy. And if that's the case, then we must really be products of our environment in an (currently) incomprehensibly large chemistry equation.
If any one decision could be quantized, reverse engineered, and then predicted through such means, then it stands to reason every decision can be. And if that's the case, free will cannot exist.
Now here’s an interesting take.
In principle, one might be able to predict behavior based on this model.
But I would asset that it is not possible to achieve these conditions no matter what godlike technology one has.
Let’s go simpler. We don’t want to predict a human we want to predict the path of one electron.
Starting from initial conditions we should be able to predict the path of that electron right Wrong!
It’s wrong because it is impossible, in a way that cannot be overcome in this or any universe, to know those initial conditions.
And that may seem like a technicality, but that’s exactly where the chink in the armor is: no matter how precise your model, it’s impossible to determine the state of a closed system, because it’s closed, and it’s impossible to predict the behavior of an open system, because its evolution is determined by its interactions with its surroundings, and you can’t get all that information.
So the idea of using physics to predict things precisely is a Platonic ideal, not a thing which can manifest in reality.
I think this is my favorite answer so far.
