Hmmm.. according to the string theorists, space-time
is ten-dimensional. Therefore, it's meant to be played
by eleven-dimensional creatures. Maybe there's a cheat
code hidden somewhere in the sixth dimension?

So is calling something a "thingy". So is calling
something an "n-rank tensor in k-dimensional space".
Trying to get useful information from the statement
"post-singularity level beings" is on roughly the same
order of absurdity as trying to derive general
relativity from knowing "the curvature of space-time
is an n-rank tensor" (and nothing else).

Yes, but we don't know the specifics of how any of
this happened. You might as well try and solve for a
billion unknowns with one equation.

How do we know that these creatures *evolved*? How do
we know that the Second Law of Thermodynamics operates
in their universe? How do we know that one plus one
would equal two?

You can dream up whatever kind of beings you want, so
long as they have adequate technology, and then cook
up a plausible-sounding argument for why they would
simulate us. To shamelessly steal Eliezer's
terminology, the hypothesis of a "universe simulation"
does not forbid any outcomes; it does not serve to let
us anticipate the future. It is a disguised hypothesis
of complete ignorance.
