I think parent didn't talk about consciousness, but free will/randomness generated by the brain. We already know that consciousness is lagging the decision processes in the brain (we have decided to go for vanilla ice cream 30ms before we are consciously aware). It also seems obvious to me that the human brain can generate entropy somehow (we can unpredictably go for chocolate ice cream). While I am sure that we will be able to measure with sufficient accuracy any brain process that leads to such decision while a decision is being taken, it seems that any suggestion that we will be able know the outcome of the ice cream decision a time x prior to presenting the choice (say 60 seconds) is impossible.
