recorded is nonsense.
There is no recombination of branches here, it's just that you
become identical to another version of you located in another
branch. Then, upon a new measurement, you'll spit over the different
branches again. If somehow you would not be identical to another
copy of you located on a branch where the outcome of the lottery is
different, then that means that you actually did not forget the
outcome as the information about the outcome is still present in
your memory (the algorithm that defines you).
And then you'll become Bruno, and then you'll become John Clark, and
then you'll become Sherlock Holmes and then you'll become a unicorn
and each of them infinitely many times... That's the trouble with
"everything thing happens" .
Yes, but this is not a problem, this is just an artifact of
introducing an unphysical "you". All that really exists are algorithms
and they can be identified by the particular computational state that
refers to them uniquely. So, your statement reduces to the fact that
I, Bruno, and many other persons exist, which is not all that
shocking.
Right. But it destroys the indicial meaning of "you" so your so your
statement that, "... it's just that you become identical to another
version of you located in another branch." becomes meaningless.
Yes, we need to be careful with precisely defining what we mean. In
principle, we can only access information stored in our present moment.
Anything that we experience that refers to the past is actually stored
inside our present computational state.
It should therefore always be possible to reformulate all arguments in
terms of only present moments, then that leads to convoluted argument.
But I think this is a good way to go about things, also in the other
thread about Bruno's duplication experiment to eliminate assumptions
that are not physical.
