How much is a human worth?

This will be the first invitational post for Hyperjumping. My friend Nuno Reis is a computer scientist with a thing for cinema and science fiction who is now exploring marketing to manipulate the minds of others (yes, he turned evil). He usually writes about the fantastic in SciFiWorld.pt, and about Technology in blog.nunoreis.pt. We hear all the time that a human life is priceless, but no one speaks about the value of humanity. Everyone is talking about the robots and Artificial Intelligences that will take our jobs, but no one is considering the jobs that will remain human forever.
