I don’t think the claim that human desires/emotions are a deterministic algorithm has met its burden of proof. I do not claim to be sure of its falsehood.

I do claim that a deterministic computer algorithm is incapable of having emotions or desires.

If there was a repeatable and testable way to get a human to produce the exact same emotional “output” for a given “input,” that would go a long way toward convincing me that human emotions are deterministic.
