Or, perhaps we are indeed living in a Bostromian simulation. QM is used at
the microscopic scale of the simulation, and for computational economy GR is
used for macroscopic modelling (stars and planets and satellites and
Buicks). While both are true descriptions of reality (in that the simulation
does actually utilize them as in model), they are in actuality incompatible.
There *is* no unified theory, and we will never develop a successful theory
of quantum gravity because there isn't one; the microscopic and macroscopic
run on different rules.
