Yes, but if you believe in the MWI (Many Worlds Interpretation)
of quantum mechanics---to which a majority of cosmologists
subscribe---then even if this is a simulation, this is also
quite separately a different and real world among the many
worlds.

In other words, the token "this" in the previous sentence
is not an unambiguous pointer, but is in effect a multiple
valued function. When we say "this" world, we mean both
the real one (somewhere) which we are in, and the simulation
(which also exists in the multiverse). We are equally and
identically in both. And have to be.
