Zoom out far enough and nature and nurture are unified into a deterministic historical timeline. Freewill is an illusion and the universe is a static four-dimensional entity.
Also, how can we say anything about free will when we have not come to grips with defining the hard problem? Of course, if you want to model biological processes based on deterministic physics then free will does not exist. I’m simply suggesting that the fundamental assumption that are universe is deterministic is flawed.
Not really. A wave function propogates in a perfectly deterministic manner. There's not anything probabilistic baked into QM.
Probability comes in at what's called the Measurement Problem. Right now, we ad hoc apply the Born rule to project complex amplitudes into probability distributions whenever convenient, but there's actually no good understanding of why the Born rule works at all. It's just sorta tacked onto QM at this point.
