As a roboticist I know that theoretically almost everything id possible for a machine. Even belief is possible (subject to what definition of belief we are going to use).

As a man I doubt that a machine could ever savor the taste of victory, enjoyment of savagery, or the crush of defeat, the anger of betrayal, or the fear of looking into one's own self.
In the end a machine will start learning what we teach it. I think machines might find complicated emotions because we as a society place too much value in them. But they won't find the primal drive of a human because we as a society underrates it too much.
