Indeed. Another illuminating passage is that Everett *did* compare the observer with an "amoeba with a good memory", and thus did relate the QM subjective indeterminacy with the comp first person indeterminacy, ... and then Wheeler asked him to suppress that passage!!! That makes it still a bigger mystery for me that Everett did not see the simpler "comp immortality", and the necessity to derive QM from number theory ..., and this despite Everett's interest in computer science, as the paper also illustrates well.

That is indeed a very thorough and interesting biography. I thought this passage was especially telling with regard to the philosophical implications of the MWI (from the page on Keith Lynch recollections):

On the everything-list we have had many discussions of this thesis, which we call Quantum Immortality, and the related idea of Quantum Suicide similar to that practiced by Lynch's daughter. It is indeed disturbing to see that someone has actually practiced Quantum Suicide, especially when the particular method used seems unlikely to be successful even with the assumption of Quantum Immortality.
