Even Physicists Don’t Understand Quantum Mechanics

The important question here is how do you know you find yourself in the cat universe more often? How can that possibly be measured? It's a difficult question when it comes to conscious experience.

Imagine instead of a single experimenter observing a billion possible outcomes, a billion experimenters observing a single possible outcome.

I propose to measure this by writing down the results on a piece of paper, and then counting them.

The hope of MWI is to produce a simpler theory by eliminating an axiom. If this forces us to axiomatize "conscious observers" then it has already failed. Though I admit it may be fun to think about.

That's the funny thing, MWI works perfectly fine without conscious observers. It's predictions match other QM interpretations. The problem comes from introducing ourselves as a conscious observer and trying to understand what it means to be consciously aware of a single outcome.

Yeah, this is indeed the key question.

My guess would be that they are all consciously experienced, some more and some less. The alternative seems to be to say that they are so called "p-zombies". Very similiar to us, evolving according to the same laws, but not concious. But it's really up in the air.
