I seem to remember reading a while back that you were saying that the
1p consciousness arises necessarily from the many paths in the UD. I'm
glad to clear up my misunderstanding.
However I don't understand how Mary could have anything but a single
continuation given the determinism of the sim. How could a
counterfactual arise in this thought experiment? Can you give a
(I got both your replies btw)
