I recently watched Ex Machina. To avoid spoiling the movie for everyone, I'll give a brief summary of the plot; A coder at a large company is selected to test an artificial intelligent robot. Over the course of a week, he has to decide whether he feels likes he's interacting with a human or a machine. This movie got me thinking. I don't know the direct quote, but one of the characters basically said AI Robots are the next step in human evolution. I personally think that the human race's ability to make their own decisions and think for themselves is what makes us human. Free will essentially. So if a robot can have free will, it's human in the most moral aspect. Physically a robot will never be human, it's synthetic, not natural. But if a sentient artificial intelligent robot can willingly believe in god, or make a decision on their own, mentally it's essentially human. What are your thoughts?
