Even if the evolution rule is deterministic, it's still epistemically/indexically nondeterministic from the perspective of the observer.
Quantum events in the brain would decohere almost immediately, leading to effectively nondeterministic behavior at any scale above the cellular. The philosophical determinism of wavefunction realism (which is the LW argument) is irrelevant to the actual behavior.
