I like humans as they are. I prefer to use robots to do jobs. (they don't mind) I hope some crazy humans do not start talking about "robot rights" or something like that.
I'm not afraid of extended artificial minds taking over the world, because they won't have the desire to dominate. This is a human desire, based on body weaknesses and deep childhood fears. Machine-minds without imperfect insecure bodies will not have to develop the fears, that make people power-hungry. At least, I believe so.
So cheers, it's good that we are getting closer.
