This is slightly off at a tangent, or at any rate a far extrapolation from, your original point, but: suppose we ever "build" something that passes the Turing Test. "Build" in quotes because I think such a think is more likely to come from a not very controlled evolutionary/growth process than from any kind of top-down design - shit, sentient perl! - than from any kind of top-down design. And therefore "God" for some value of the term is agruably involved.
But anyway, if such a thing does come into being, being the product of a human-initiated process, is it then in any sense a "person" entitled to respect?
Note that I don't think this is on the verge of happening. I am not some kind of Kurzweil-style millenarian loony.
