I think arguing about Free Will is a waste of time, so I'm going to make this brief. Free Will is purely an invention of people who don't understand the laws of cause and effect, or it is redefined into meaninglessness. Additionally, it adds no value to our conception of the world or of humans.
Just because the idea gets me mad, I'll ask this question to Free Will supporters: if you had a robot, a human, and a chimp, and they all did the same thing when exposed to the same stimuli, how could you tell which had Free Will?
If they all acted differently, would you be able to tell which one had Free Will?
In other words, how can you tell if something has Free Will? And if you can't tell, what value does the theory have?
