One common response to this view is that A.I. experts are particularly worried about learning machines, and that something about the complexity of these systems gives rise to emergent properties that are
metaphysically irreducible to the sum of their parts.
In connection with the question of the evolutionary origins of man, the Church's teaching emphasizes that spirit and matter are not the same, that spirit can not be derived from matter, and that man, because spiritual, has
a metaphysically irreducible position in the cosmos, so that his origin, as far as his spiritual nature is concerned, can not be found in matter.
