OK. Do you agree now that the "real Torgny", by which I mean you from your first person point of view, cannot known if it belongs to a state generated by automata 345 or automata 6756, or automata 6756690003121, or automata 65656700234676611084899 , and so one ... Do you agree we have to take into account this first person indeterminacy when making a first person prediction?
