Boil it down even further than OP and everything, ultimately, is just binary impulses between differently oriented clusters of atoms.

Time and time again I find myself coming back to a deterministic interpretation of the physical world. We're now at the point where a simple scrape-predict-regurgitate AI language model (ChatGPT) can convincingly imitate the communication pattern of a human being with good factual recall but low social acumen, almost like what we generally associate with the autism spectrum. It's harder and harder to argue that we aren't just walking flesh bags with simple electrical impulses that carry us from decision to decision based on a finite dataset. It's amazingly complex and sometimes can seem unpredictable, but it's still finite. Were we ever able to build a sufficiently complex computer, I believe it could predict every decision we ever make with remarkable accuracy. The concept of "free will", at least to me, seems a comfortable agreed-upon illusion that keeps us from killing and eating one another.

Depends on the temperature and pressure.
