Simulationism is basically just like a religion- it is a set of beliefs based on no actual evidence. While the right of people to believe as they wish should be respected, the belief itself deserves no respect or serious consideration unless it can be logically backed up with substantive evidence.
"Solomonoff's theory of universal inductive inference is a theory of prediction based on logical observations, such as predicting the next symbol based upon a given series of symbols. The only assumption the theory makes is that the environment follows some unknown but computable probability distribution. It is a mathematically formalized Occam's razor."
