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?
