We, the human race, say a robot can be superinteligent, but it will never be able to be alive nor to have a soul, right? But, is it relevant to them? in the end, to be alive and having a soul are concepts designed by humans which suit us, in any case suppose God's existece, he/she/it has "something" we don't have, is it that relevant to us what God has?
In the end what really matters is to preserve the specie and its whole inteligence, the same can be applied to robots which want to replicate, to them, the concept of being dead or alive can mean less or nothing. All the philosophy is by humans for humans, a robot can develop its own phylosophy and have concepts that could be incompatible to the human existence.
