The Many-Worlds Interpretation Has Many Problems
&gt;What can you do with this power to generate worlds and selves? You could become a billionaire by playing quantum Russian roulette.<p>Quantum suicide isn&#x27;t exploitable, for reasons I went over in a thread on reddit:<p>&gt;One thing about these quantum immortality (or modal realism, dust theory, etc.) arguments is they imply one should expect to end up in those proportion of worlds that have the highest measure in which &quot;you&quot; exist. And the most probable actions you should expect to remember are the highest-measure actions that leads to the perpetuation of your conscious experience.<p>&gt;In this way quantum suicide is not really exploitable, as the vast majority of &quot;your&quot; measure will be in worlds where you find quantum suicide to be unappealing. Even failed attempts will be of much smaller measure then those in which you never try. So stories like Permutation City are sort of the equivalent of stories in which magic is the result of quantum fluctuations. They don&#x27;t violate any laws of physics but they focus on such a ridiculously myopic slice of possibility space that it is a little absurd, even when you condition on the continuation of conscious experience.<p>Even if it were exploitable, this is not a reason to doubt many worlds, any more than time dilation is a reason to doubt relativity.<p>This great comment on that piece by Sengachi is a must read: <a href="http:&#x2F;&#x2F;disq.us&#x2F;p&#x2F;1wnl71q" rel="nofollow">http:&#x2F;&#x2F;disq.us&#x2F;p&#x2F;1wnl71q</a>
