Thank you, we should have remembered that zig-zag approach!
Yes, that's the dovetailing, and we cannot avoid it because there is
no algorithmic procedure to decide if a program (with or without
input) will stop or not (the logical price of Turing completeness). So
we zig-zag among them indeed, and as the others said, this ensures
that all accessible computational states will be generated soon or
later. Obviously, there will be greater and greater delays (measured
in some UD-step "time") between the states of each computation, but as
you can guess, this does not change the first person indeterminacy, as
it explain in step 2 and 4.
Note that if the universe was a one-branch universe, the probability
is near-zero that we are not generated by the UD, as it contains
(generates) the infinitely many computations going through our states
infinitely many times. Indeed the physics has to be retrieved from
that statistic on the UD* (the work of the UD). Same with a concrete
multiverse, although this is less obvious, and perhaps more debatable
a priori (as Russell remarked once).
Nice to hear from you and Liz,
Bruno
