Episode notes

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.

Welcome to the July 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic.

We're experimenting with a new benefit for Patreon supporters: short video (or audio-only) reflections by me on the podcast that just happened. If you've been wondering whether to join up, this could be the time.
