I also wanted to discuss your point about the finite set of top AI researchers. I think their specific psychological biases have the potential to appear and magnify inside the personality of their AI, the way a work of art can be said to imbue the 'spirit' of its artist. Your thoughts would be appreciated.
But I don't think a hypothetical god-AI is likely any time soon. And a hypothetical god-AI is just as likely to be indifferent as hostile.
What worries me more in the short term is cyber war. Cyber defences that might protect against a hypothetical non-god AI look a lot like cyber defences that might protect against conventional human threats.
Currently those defences are ridiculously weak.
So I think rather than hyperventilating about science fiction threats from the distant future it would be more useful to start securing the entire Internet as a matter of urgency - especially all the infrastructure systems that are either connected to it already, or will be connected to it soon.
Rather, let's take a cue from Nassim Nicholas Taleb and in concert with the progression of AI, develop counter systems that make us less fragile. It shouldn't be unreasonable to extrapolate where AI is headed in 1, 5 or even 20 years based upon publicly available research.
Which brings up the most crucial point. The subset of humanity that constitutes world-class AI researchers is very finite indeed. Which brings up the significant possibility of a Bane / Dr. Pavel scenario playing out. Not unlike certain coerced atomic scientists in Persia today.
