That's because the world that they are modeling is actually not
digital, but the model itself still is. If there is a machine
intelligence in there, we know that it must live in the world that we
give it to sample digitally, whether or not it can produce output
which we interpret non-digitally. It's back to symbol grounding again.
I have a digital CD playing on a digital receiver. The acoustic
drivers are digital too. The music is not digital. The CD, the
receiver, and the speakers cannot hear the music. We can safely reason
that they probably do not hear the music, yes? We can assume though
that they must sample the CD digitally though. That we know for a
fact. That's all we know for a fact. If the same were true of us, we
would have no real reason to listen to a sequence of digital codes,
but if we did there would be no reason for it to sound like anything
other than a sequence of digital codes. It should sound just like it

It's not about being able to tell the difference, it's the fact that
there is any sensory experience at all. Any kind of sensory experience
is redundant if you have a digital information transfer. It would be
functionally useless and physically implausible to the extreme.

God, Chief Engineer, evolution, logic, whatever.  Why does it make
sense that sense exists if you don't functionally need it?

Ugh. Not extended beyond *our* sensory abiility... extended beyond
*their own* sensory ability. We can't see gamma rays, but we figured
out that they (sort of) exist. Do Geiger counters ever figure out that
they are missing the visible spectrum?

Yes. I know.

That is the assumption I'm challenging.

Of course.
