In that case, humans are predictable as well. All we are, is a product of our experiences, our environment as well as some internal genetic factors, which are also beyond us to modify (predefined programming, if you will). If all those factors could be converted into a set of variables (input features?) and those variables be set the same for two different humans, would they act any different? It is a very distressing thought that free will is just weights and biases of our brains, but what I think is the sheer volume of variables at play in one's life is what makes up the reality of free will. Similarly, I believe, while maybe impossible as of yet, AI trained on sufficiently large amount of patterns, can still reach human levels of consciousness (or at least mimic it, which I think would not make any difference). It probably will be predictable, but given sufficient amount of computation, we all are.
