I'm not sure what you mean. Anyway, I might have. My proposal is on my
web page in the Plank Syposium paper

What, that his measure was reduced? Surely you heard that news.
To be precise, if the fact that he might die this way was something we
anticipated, then indeed his total measure would be reduced by the event,
but our knowledge of that reduction would not depend on our being in the
world where he died. So we would not have extra reason to feel bad about
the reduction. But this news came as more of a surprise, wouldn't you say?

I don't know what you mean. A couple of points though: 1) You know that
as I've said before, Everett's memory-based formulation is not
computationalist and IMO he would have readily admitted that it was only
meant as a preliminary ansatz to start studying the MWI. 2) The
nonrelativistic setting surely includes space and time a priori.

I never did anything like that, & have no clue why you think I did.

Obviously. Any preschool kid should know that, so why do you bring it
up now?
>Why do you put "many world" in your signature?
I put "Many Worlder" to let people know a little about my beliefs.

Eh? Why do you ask?

Depends what you mean. Are the numbers 5 and 6 identical? I don't
think so. But look on a number line at the internal structure of these
points. They look the same. They're just located in different spots, in
this case in Plato's funhouse. Same with two different implementations of
the same computation, whether in Plato's funhouse or a physical world. If
you disagree and say they are the same, give me $6 and I'll give you $5.
