Do machines evidence emotion. Universally not. We have a chasm here that the Materialists have tried valiently to bridge for decades. Without success. Quantity and complexity won't get you there. Maybe there's a reason for this that goes quite beyond the material. I clearly think so. The day Materialist Science is credibly able to attribute emotion to a gene or set of genes will, I feel safe to say, never come. You feel safe because you are whistling in the dark. I do not expect to win any arguments by assertions about the future (didn't I just say we can't do that?) but I can still register my bet. Attempts at "artificial flight" were first documented by the Greeks. It took thousands of years to perfect. You will need at the very least, a new law of physics, to demonstrate that machine intelligence and machine emotion are impossible.
I won't grant you thousands of years. Bad ideas are bad ideas.
