These are great questions. Some might think that creating AI is proof of idiocy. If the programmers tell AI we are its creators, then we'd ave to define "creator" in a theological sense, which would bring us back to the cluster f*** we currently enjoy. In other words, I clearly have no answers for these great questions.

I hope so.
Could be so much fun.

Captain Kirk can always defeat Darth Vader.
He'll just wait until Vader has to install the latest upgrade to his robo-suit.

Will eventually want to fix us and will decide to disassemble out bodies to try and make us perfect.

Doubtful. There are too many advances beign made to variosu companies for Asimov's "rule fo robotics" to be hard wired into artificial intelligence. Without those rules in place a "Terminator" future is not entirely impossible.

Through my experiences in software development efforts (including software that learns) I understand the error detection and refinement loop will prevent repeated software failures which eliminates idiocy. Another factor that contributes to idiocy is degradation due to environmental stress for both biological and electro mechanical systems. Nanotechnology will provide sufficient degradation (physics of failure) detection to allow for timely prognostic reponses which facilitate continuous optimal systems availability. Put in human terms transhumans will have perfect health and immortality.

AI will consider us it's parents in the electro-mechanicanical sense then we will be quickly dismissed as flawed in current biological form as a step along the the path of evolution. The most important existential question in this epoch will be whether we (machines and humans) choose to merge or not. There are humans (Ray Kurzweil and other futurists) already dedicated to preparing for the merge.

Flawed info in, flawed info out !

Terminator is a very real option which I thought when I first sore it. people are already driving into rivers with satnavs lol.

John Conner is going to have to come save us.

Isn't he?

And that bullshit initial thing.

That's a really interesting question, I unfortunately do not have a strong opinion either way of how that might play out.
I have however pondered similar questions, do you think that one day technology and life may become so intertwined that we won't be able to tell where one point stops and the other begins? With the advant of technologies such as microrobotics in the medical field, I think this is also an interesting question to consider.
