Do you think a river has free will?
Like rivers we just respond to information/feedback.
The feedback we receive as human, has many more dimensions than that recieved by a river. Therefore our response has far more possibilities than that available to a river.

I do not believe that everything is predetermined, I believe we have purpose, I believe we are looking for an answer to a problem. We are wired to create in response to our environment the same way as we wire up AI. DO you suppose that AI could develop free will? I am quite sure we will create the illusion of AI haveing free will.
