Having a random quantum seed to an otherwise opaque internal process is still a far cry from free will and agency.

Consider thermodynamics: even without quantum weirdness, we can't compute/predict the micro interactions of atoms in a gas. But most average out, and we can make a lot of meaningful predictions on a macro scale.

Back to brains: even if there is some underlying quantum process that might free us from full determinism, on a macro level, it might not matter - you're still gonna value what you value, and make the same "choices".

And if in some cases a "decision" is actually impacted by some quantum effect... is it "agency"? Or just yet another external process affecting us?
