The Emergent Multiverse
I thought many worlds got rid of such subjective macroscopic concerns. I don't think it's true that many worlds gets rid of a macroscopic element in or a subjective element in how we describe the universe. At some level, many worlds is simply the statement that there are wave functions that always obey the Schrodinger equation. That's why David Wallace's book about many worlds is called the Emergent Multiverse. And when things are emergent and higher level, there will be subjectivity that comes in as well.
