You are not helping me very much, here, George, :-(

You could have said <<How do we make precise what amounts to
ramble. And how do we leave the field of Metaphysics and enter
the field of ...Information Science, or Engineering ...>>

I guess it's my fault. I should have read more carefully one of your
where you ask for an explanation. Here is your post :

Put in these termes + simplifying a bit,
what Maudlin and me have showed is that

EITHER the appearance of hardware and consciousness
is explain(able) by the theory of possible softwares (computer science,

OR the computationalist hypothesis is false.

That is why I ask for, ultimately, a serious consideration on Church's

I agree with Wheeler that physics cannot explain the origin of the
laws, by itself. Physics inspired without doubt our issues, but physics
per se
doesn't help for in some sense physics IS the issue.
