Current AI offerings fall far short of superintelligence, which would arguably require genius-level ideas and world-views at least as rich as our own, including, for example, high quality evaluation and representation capabilities, in addition to very powerful hardware. They also lack other important things such as consciousness and even a sense of humour.
So humans stand apart from the most advanced machines physically but also psychically. The differences are primarily spiritual. Man-made superintelligence would challenge world-views which involve God and they would impact significantly on our human world-views in general.
Does all this rule out the possibility of their existence?
"Man-made superintelligence would challenge our world-views… and superintelligences would have to be aware of those world-views. They could only do this properly if they had their own world-views. Their world-views should then include us, and of course our world-views should include them."
