"The set of humans minds might possibly be outside of the set of possible Strong AI minds"
Uh, you know what the 'A' in 'Strong AI' stands for, don't you?
You may choose to ignore the etymology of the term, and include humans in the set of Strong AIs, but that's not the generally used definition of the term, and I'm sure that the original poster, the poster I responded to, and pretty much everybody else on this thread was referring to non-human intelligences.
Therefore, my points stands: if you were to exactly replicate all of the features of a human, you would have created a human, not a non-human intelligence.
If I replicate the brain algorithm of a human, but I do it in some other form (e.g. as a computer program, instead of using carbon based molecules), is that an "AI"?
If I make something very very similar, but not identical to the brain algorithm of a human, but I do it in some other form (e.g. as a computer program, instead of using carbon based molecules), is that an "AI?"
Its a terminology discussion at this point, I think.
In my original reply my intent was "provided that there are no souls/inputs from outside the universe require...
If Strong AI turns out to not be possible, what are our best expectations today as to why?
I'm thinking of trying myself at writing a sci-fi story, do you think exploring this idea has positive utility? I'm not sure myself: it looks like the idea that intelligence explosion is a possibility could use more public exposure, as it is.
I wanted to include a popular meme image macro here, but decided against it. I can't help it: every time I think "what if", I think of this guy.
