> None of these humans "want" to do anything. They respond to specific input

Weird, because I'm pretty sure I had the choice whether to respond to this comment.

It wasn't the light waves hitting my retina from an HN post, leading to nerves firing and neurotransmitters all coming together to post this.

I posted it because I have free will. I almost didn't.

Unless you truly feel that there is no free will, and that reality is just a bizarre movie we have to experience .... well, then ... we'll disagree.
