He assumes that consciousness is a simulation from the start though. If you do that, then it seems meaningful that the simulation fits so closely with reality, whereas if you understand that sense is what reality is made of, then it's not a surprise. If consciousness has a survival value, then surely omniscience, teleportation, or the ability to turn into a diamond on command would have an even greater survival value. What he admits is the problem of identifying the casual (?) effect of consciousness in it's own right is not a problem, but a symptom of failing to see that causality supervenes upon sense and not the other way around. Cause and an effect are a kind of sense, arising from subjective memory, pattern recognition, and world realism.
