I'm not sure what you mean with your distinction between living and
non-living, but it seems that you can get living from living,
computational from non-computational and intentional from
non-intentional. If you want to say that the non-living,
non-computational and non-intentional already had a dormant form of
the quality they were lacking then you could say that but I don't see
what it adds.

The claim is that the physics explains all of the physical activity. A
door does not open unless someone or something pushes it, whether it's
a person, a gust of wind, the reaction from a decaying radioisotope
in the wood, or whatever. If the door is a little one inside the brain
that does NOT mean it opens without any identifiable physical cause.
If the little door opens in response to a joke it is because the
physical manifestations of the joke (sound waves) cause some other
physical process which makes it open. It does NOT open because the
joke just magically makes it open, which is what would appear to
happen if consciousness had a direct causal effect on matter.
