I think that Turing was implying that a group of engineers of different
sexes would be able to create a machine through normal reproductive
which would lead to us having gained no ground, as we would have learnt

I am not sure this is what Turing is doing at this stage. I think he
was eliminating the possibility that the engineers could simply use
cloning to produce a machine that had a mind.

I agree that a lot of the attributes mentioned in this argument have
to do with intelligence but are simply trying to imitate humans more
But for a machine to pass the Unrestricted Turing test, does the machine
not have
to be Indistinguishable form a human in every way. I agree that the
machine can
learn from feedback from its actions, but is this really experience. I
think that
experience implies that the machine has actually understood what has
happened, and as
a result updated its self in some way. A machine cannot fully
understand what is
happening until it has been grounded, until then it is simply following
supplied by its program.
