Yes, I agree.

Hmm.. Sounds like we might be talking about different things. Or maybe it's
just our terminology...

To be clear, I envision just one universe that contains everything. Within
it may be many worlds or sub-worlds, but these are not independent. They

Furthermore, I imagine there is a single program that runs the whole
universe, and that we can know that program exactly.

I'm not sure what Godel is doing here.

As in fine-tuned to support life, etc.? No, I don't see any necessity in
that either. Where there is life, there is life. That's enough for me!
