His decision making options are restricted
What is free will if not decision making? I understand people who say free will doesn’t exist as saying we don’t actually make decisions, it’s all decided for us by some other factor.
The ability to predict things does not negate free will. If I put a ball on a hill it will roll down because it has no free will, and I am able to predict that. If I offer you $20 or a punch in the face I am able to predict that you will choose the $20, but that doesn’t mean free will doesn’t exist because you could choose the punch in the face.
I am 100% sure any ball will roll down the hill 100% of the time. I am only 99.99% sure that any person will choose the $20 100% of the time, because humans have more free will than a ball.
This is certainly one interpretation and the one I generally use but it’s still an an abstraction based on sentiment
Chatgpt can make decisions based on past “knowledge” and external stimuli, but we don’t consider it to have free will
You could say that’s only because it can’t do anything without human input but we can’t do anything without input from our senses
