"Emulated" would mean we're "really" computed somewhere else.

Explain to me how being emulated in the universal dovetailer is 
different from being  simulated by a computer.

Re: Do we live in a (computer) simulation?

[Brent Meeker]

I think Sabine is wrong when she says that one must use qubits to
compute the universe.  Anything computable by a quantum computer is
computable by a classical (Church-Turing) computer, with the penalty of
an exponential slowup.  Sabine makes some good points, one of which I've
tried to make with Bruno.  Bruno (and Tegmark) aren't thinking of a
physical computer (as Sabine apparently is); they're Platonist and
they're thinking of a Turing machine or other abstract "computer" that
computes everything.  Bruno likes to cite a set of Diophantine equations
that constitute a universal computer.  But as Sabine observes, the
computation of the universe can't just be a computation of your
thoughts.  In order that your thoughts be "about" something, the
something must be computed too.  There's no other way to assure that
your thoughts will correspond to a universe.  But then we're back to her
first point that of course the universe is computed in this trivial
sense that everything is computed.  I think Bruno understands and
accepts this point, but he sees his theory that every possible
computation is performed (by a universal dovetailer) and our multiverse
is just one of the things computed as an explanation that is beyond
trivial.  He says it implies quantum mechanics via the
first-person-indeterminancy principle. I think that's still trivial.

Where does Bruno say we are living in a simulation? He says we are more likely 
emulated.
