Difficult remark. Perhaps we need a satisfying relativistic account of
MWI.
But we don't even really got a satisfying relativistic QM.
Even with 'just' comp, merging is important. I agree. It is also the
existence of merging which make the search for a measure so much
difficult.

My first idea to get an understanding of the first person view of merging
was to made the mergers amnesic, a little like the quantum eraser.
But amnesia with comp still lead to multiplication of possible
continuations.
The Galois Connection between models and theories strikes again!

You point on difficult matters here, Gilles.
