While I'm a supporter of Tegmark's Ultimate Ensemble, I think it is by no
means clear that just because everything that can happen does happen, there
will necessarily be a world where everyone becomes omniscient, or lives for
ever, or spends their entire life dressed in a pink rabbit outfit.
"Everything that can happen does happen" is not synonymous with "everything
we can imagine happening does happen". Worlds where we live forever or
become omniscient or are born dressed in a pink rabbit suit may not be
*logically possible* worlds. Just as there is no world in the multiverse
where 2+2=5, there may be no worlds in the multiverse where I live forever
or spend my entire life dressed in a pink rabbit suit.
