It's an opportunity.

You can maybe learn something and maybe even solve some puzzles that pre-existed the existence of your theory.

In particular, just to say it very, very quickly, because we're going to say it at great length soon enough, in the case of Everett and Many Worlds, I think that there's a big puzzle about basically the fact that the theory is too simple.

I know that people say that Everett is very complicated.

It violates Occam's razor because all these different worlds out there.

But if you know what the theory actually says, it's a very, very austere, simple, pretty formalism that

so austere that you really don't recognize the real world in it when you look.

And so I will explain what I mean by that.

And I will explain how I am nevertheless optimistic that we can find the real world lurking there in the Everettian quantum state.

At least I think that we have reason to believe that that project will turn out well, but it's not done yet.

So we could be wrong.

And if that's true, then we'll still learn something.

So let's go.

I want to start with two caveats or warnings, I suppose, which is never a good way to start your talk.

I know.

I always give that advice to never start with apologies, and then I always do it myself.

So, you know, do as I tell you to do, not as I actually do myself.

But the two apologies are this.

One is it will get a little technical at times.
