Who really believes in determinism these days? The people who believe that one day, should we have enough inputs we could make provable predictions about the behaviors of sentient beings? That AI will become fully conscious like a human? I don't claim to be an expert in the area, but it seems that non-determinism in nature seems to rebut that possibility. At the subatomic level, to a systemic level. Meanwhile the idea of a deterministic universe masked by a fake belief in in our own consciousness is something of a deeply pessimistic thought. If we everything has been determined, and you are just an observer within this deterministic vessel, then there's absolutely no reason why ethics should have any consideration, among other problems. I'll just settle on the existential dread that I've been making the wrong decisions...
