As pointed out in earlier post: With that move, it is no longer

question is
nonsense, no indexical property, there is correct substitution
level, all
possible 1p consciousness of all persons supervenes on the recording
(everything digital) *or* none at all since recording has no CC and
other
such funky consequences I can't recall. How is this avoided if
everything
is one bland sauce of digital?
It is not at all obvious that counterfactual correctness (CC) is
required for a computation to be conscious. Bruno usually argues that
feature is a red herring.
I do that in some place, but this is really what Maudlin showed, when
keeping materialism and computationalism + the idea that something
inactive in a brain during a specific computation would not change the
specific consciousness if it were removed. I do that to get the
absurdity.
But I keep comp, and counterfactual correctness is a bit of the
"essence" of what a computation is. It is what make absurd the idea
that a movie could be conscious: it does not enact a computation. It
does not need a universal machine to be enactedn unlike any computation.
The same movie could correspond to different computations, if we
change the universal machine which did that movie, and build an ad hoc
different one.
If it is, then non-CC recordings are not
conscious, and the MGA goes through in the small (non-robust) universe
case. But recordings can also be counterfactually correct in principle
by adding the inactive Klara? Then we are again back to Maudlin's
point. neurons must know which neurons did not trigger them. They need
some telepathy.
(in the form of a huge lookup table, for example, in Searles's Chinese
Room), or in the form of a precise specification of the quantum wave
function, or of a finite chunk of the UD* trace.
You mean description of them, or they actualization or realization by
some reality (arithmetical or physical).
You might be slipping from the computation to its description.
Bruno
Modulo the no-cloning
theorem, or the Seth Lloyd limit which would prevent such a recording
existing in our current universe.
Thanks for pushing the question though Russell, as my earlier posts
were
perhaps less clear on this. I guess you're coming from some ground
I can't
parse or have missed reading and you have my apology here if so. But
zombies can be tricky bastards :-)
Where do you draw the line? I'm afraid
intuition does not help much in this matter, which is why I say
it is
a weakness of the MGA.
There must be something more to it than just complexity or even
Turing
universality. Bruno says human-like consciousness requires
Lobianity. But
I think that's asking for more than just awarenss; it's asking for
self-awarness.
Which with comp assumptions/environment includes the properties
that come
with that kind of self-awareness, e.g. incompleteness, machine's
silence
etc. PGC
If I were building a Mars Rover and gave it the ability to learn
from its
experience by reviewing its memory of events and projecting
hypothetical
futures, I would be concerned that I had created a sentient being
that
would forsee its own end. So I would be sure to avoid putting its
indefinite survival into its value system.
