Sure, it would be great to have improved synthetic bodies, but I have
no reason to believe that depth and quality of consciousness is

artificiality may not affect me as much as having an artificial leg,
however, an artificial brain means an artificial me, and that's a
completely different story. It's like writing a computer program to
replace computer users. You might find out that digital circuits are
unconscious by definition.
You might find out that molecules in brain are unconscious too.
What in the brain would be not Turing emulable? You need to speculate
on a new physics, or on the fact that a brain would be a very special
analogical infinite machine. Why not?
You might still appreciate my point. I don't think that today someone
shown that comp leads to a contradiction, but comp leads to a
reappraisal of the relation between first person and 3 person, or, at
some other level, of consciousness and matter, and this in a testable
way.
But there is no problem with what you say. If you believe in
physicalism, then indeed mechanism is no more an option.
In my opinion, mechanism is more plausible than physicalism, and also
more satisfactory in explaining where the "illusion" of matter come
from. Actually I don't know of any other explanation.

Indeed, why? Any talk of 'artificial circuits' might risk the
patient saying 'No' to the doctor. I want real, digital circuits.
Meat circuits are fine, though there might be something better. I
mean, if something better than 'skin' comes along, I'll swap my
skin for that. Probably need the brain upgrade anyway to read the
new skin. You could even make me believe I had a new skin via the
firmware in the brain upgrade. No need to change skin at all.
I could even sell you a brain upgrade that looked like it was
composed of meat when in fact it was a bunch of something else. You
only have to believe what your brain presents you.

Replacing parts of the brain depends what the artificial circuits
are
made of. For them to be experienced as something like human
consciousness then I think they would have to be made of biological
tissue.
Why? Biological tissue is made out of protons, neutrons, and
electrons just like computer chips. Why should anything other
than their input/output function matter?
