Do we have enough information to create a rat? I think so. Is that an A.I.? To be rat-like you have to be able to adopt to new environments, learn new things.
Could we also model in the same way a human baby? Ok, that's perhaps a bit too hard. What if we try to create a model of a mongoloid baby. It would still be considered intelligent, right? Is it an A.I.?
Why does a system need conciousness in order to be able to dominate its environment? To me, clonable robotic rats would be as much of an inconvenience as real rats are.
