The rejection of your thesis that consciousness is an algorithm is not a rejection of determimism. I have no doubt that all that exists is only material and the properties that emerge from it. The word algorithm makes no sense without a goal for it to be used to reach. Taking your paragraph about being able to predict everything a human will do in their lifetime with sufficient information (possible in principle, but intractable), what outcome would I be trying to achieve with this information? Is there some clear end state that the consciousness algorithm is optimized to reach?
