>From the subject’s first-person perspective there is no new information at the time of wake-up. Some arguments suggest there is new information that the subject learned “I” exist. However, from the first-person perspective, recognizing the perspective center is the starting point of further reasoning, it is a logical truth that “I” exist. Or simply, “It is guaranteed to find myself exist.” Therefore “my” own existence cannot be treated as new evidence.
I agree one can’t update on existing. But you aren’t updating on wake-up—you can make this prediction at any point. Before you go to sleep, you predict “when I wake up, it will be in a world where the coin landed heads 1⁄3 of the time”. No updating required.
