content: If you start with a beast and you layer intelligence on it, you get a human.  Why would you start with intelligence and then layer beast onto it?  The idea of propagation and survival are animal ideas.  That's fine for us- we're animals that are smart.  If you make a machine that is smart, it won't have all the shitty ideas about "continued existence of the new machine race" unless WE put them there.  Why would we do that?  We don't try to make our toasters hate hands.
