Emotions play a very important role in our lives. Being human, it is the one thing that separates us from machine.
Machines capable of true emotions is the stuff of fantasy. For years, man has tried to create machines with artificial intelligence capable of exhibiting real human emotions.
None have succeeded.
But so much of our lives are run by machines created without emotion. This was clearly evident when the Dow dropped close to 1000 points in less than a few minutes, spurred by a chain reaction of computer glitches and human emotional events.
So while there is no such robot that can exhibit real emotions, there is a metal that can. We call it the human metal.
