Liz,
See my response to Brent on consciousness of an hour ago. It
answers this question...
Actually to answer your question properly you have to define
'person', what you mean by an 'AI' and what you mean by a
'simulation'. In the details of those definitions will be your
answer... It's arbitrary and ill formed as asked....
Yeah, unlike waffle about "it's really real because it's real in
the real actual world, really, because I say so" (insert eye-
rolling emoticon here)
OK, let's say we simulate you in a virtual world. Or, to get a
particular scenario, let's assume some aliens with advanced
technology turned up last night and scanned your body, and created
a computer model of it. We won't worry about subtleties like
substitution levels and whether "you" are actually duplicated in
the process. It's enough for the present discussion that the
simulated Edgar feels it's you, believes it's you, thinks its you,
and appears to have a body like yours which it can move around,
just as you do, in a world just like the one you're living in (they
have also modelled the Earth and its surroundings. Using
nanotechnology they can do all this inside a relatively small
space). The simulated Edgar will think just like you, assuming your
thoughts are, in fact, the product of computation in your brain,
and it has your memories, because the aliens were able to model the
part of your brain that stores them.
So, sim-Edgar wakes up the next morning and believes himself to be
earth-Edgar.
Would he know, or discover at some point, that he's a simulation in
a virtual world, and if so, how?
And the answer is "yes, he would know that, but not immediately".
So it would not change the indeterminacy, as he will not immediately
see that he is in a simulation, but, unless you intervene repeatedly
on the simulation, or unless you manipulate directly his mind, he
can see that he is in a simulation by comparing the comp physics
("in his head") and the physics in the simulation.
The simulation is locally finite, and the comp-physics is
necessarily infinite (it emerges from the 1p indeterminacy on the
whole UD*), so, soon or later, he will bet that he is in a
simulation (or that comp is wrong).
OK?
Bruno
Is this necessarily true if the simulation were run on a quantum
computer so the simulants observed a kind of FPI?
