But we are trying to reconcile your results with previous notions of a
"fraying" multiverse. That is, in David Deutsch's view (and MWI in general)
at any point in a universe we are inhabiting, there is a small amplitude
for almost anything to occur. Hence the "spitting off" of tiny worlds.
To what degree do you reject this standard MWI way of looking at it?

But then, I take it, most of one's experience then should be in the major
measure "airless moons" of vast mass and high probability. If so, then
this too tends to diminish expectations of getting mangled.

Besides, if I recall correctly, you or someone objected to a certain
popularization of your idea, namely that there is a reasonable chance
that after a few more years of placid existence, the world we
inhabit may get snuffed. Is that really a consequence of your theory?
