*Before the box is opened Brent Meeker#1 and Brent Meeker#2 are identical
because neither of them knows if they are in the alive cat world or the
dead cat world. It's only after they look in the box do they become
different. *

*True, and neither Brent Meeker#1 nor Brent Meeker#2 observes any sort of
superposition. And the Shut Up And Calculate people don't even try to
understand it but if you're not one of them then try to explain how in the
