But that assumes there can be a computation independent of any material
realization - a computation that never has an error. Real computations
are realized by quantum mechanical devices. Of course they may be so
large and hot that they are to a very good approximation classical (the
brain is according to Tegmark). But I'm supposing that the complexity
of conscious computation (and remember we are talking about simulating
the environment, not just the brain) is so great that quantum effects
are inevitable.
