Concepts generated by a human mind verses concepts generated by a computer. If AI ultimately reaches the level by which humans consider it "the same" then the question HAL asked? "Will I dream?" will indeed be a intriquing phylosophical question we humans will be faced with. If Human Intelligence can generate supernatural concepts from our imagination then it seems logical that machines will someday follow suit. What will be the ramifications of such a reality where machines have a machine derived god.
The scientific community has very little to do with it. That is why Thor is still a supernatural being despite the fact that science long ago made any supernatural cause for thunder and lightning obsolete to all but the most philosophically pedantic.
And you broke my balls in the past for saying that Science is silent in matters of faith.
We can infer the only source of supernatural beings is the human imagination. But without a way to evidence this by employing a physical test to the subject we can not scientifically conclude this is so. Although I agree I personally have never come into contact with a supernatural being other than that which was fabricated by someones imagination.
