The how is Solomonoff induction, the why is because it’s historically been useful for prediction.
I don’t believe programs used in Solomonoff are “models of an external world”, they’re just models.
Re simplicity, you’re conflating a mathematical treatment of simplicity that justifies the prior and where ontological claims aren’t simple, with a folk understanding of simplicity in which they are. Or at least you’re promoting the folk understanding over the mathematical understanding.
If you understand how Solomonoff works, are you willing to defend the folk understanding over that?
