  • Tegmark's multiverses and related cosmology and the manyfold implications thereof (and the related simulation argument).

In what areas are these implications? In particular, what are the implications for existential risk reduction?

I recently read "The Mathematical Universe" and this post but so far I haven't had any earth-shattering insights. Should I re-read the posts on UDT?

We could be getting most of our measure from all sorts of places, which means that maybe a very small proportion of our measure is actually at stake. If all computations exist, some of those computations have preferences over other computations that include us. It might be good to understand such preferences. That in itself has many implications. But I guess I'd say that it's easy to go funny in the head when thinking about things like that, so be careful.
