Bruno,
Is it possible that as all my copies strive towards better
outcomes, the entire group advances? If the worst are always proportionately
opposite to the best, and the best keep improving themselves, don't they pull
the worst up with them? Just a hopeful thought. M.A.

Hi Bruno,
I'm quoting your response to an older post because I have a
residual question. If "I" improve my ability to select the best future
outcomes, don't "I" also choose the worst ones according to MWI and the rule of
sum-over-histories? I seem to be competing against myself. M.A.
Assuming just Everett QM, there is a notion of normality and classicality
which can be derived from the quantum evolution. This is expalined by david
Deutsch, but also the "decoherence theory". So, when you take a (classical)
decision you will act accordingly in the vast majority of your histories, and
very few version of you will accidentally be doing the opposite.
Taking into account the comp. Hyp. such "decoherence" has to be refined a
priori, and this leads to a gallery of open problems.
Both with QM without collapse, and with comp, such normality is hard to
justified from the first person views when we are "near death". This leads to
even more complex questions. I can only say that I don't know what happens, but
I do expect, some probable "jump", guided by some theoretical computer science
intuition. Some backtracking of experience, and renormalization of
probabilities could also occur.
Many-histories is not "all histories", or it is "all histories" but with
different relative weight. We can't use MW for escaping our "responsibilities",
I think.

At some point I could "defined" consciousness as the state of
(instinctively at first) betting on a history. This will speed up yourself
relatively to your current stories, and make greater the set of your possible
continuation. As an exemple you become aware an asteroïd is coming nearby make
it possible for you to envisage a set of possible decisions, which can
themselves augment your probability of survival.
