Actually, one doesn't need to assume substrate independence - simply that
our own level of reality is one that can be simulated by our enclosing
universe. We may lose out on all kinds of unimaginable ontological
characteristics by virtue of our mere simulationness; we just don't know
what they are, of course, being mere simulations.
