Paragraphs like these is why some people don't like SlateStarCodex

So superintelligences may spend some time calculating the most likely distribution of superintelligences in foreign universes, figure out how those superintelligences would acausally “negotiate”, and then join a pact such that all superintelligences in the pact agree to replace their own values with a value set based on the average of all the superintelligences in the pact. Since joining the pact will always be better (in a purely selfish sense) than not doing so, every sane superintelligence in the multiverse should join this pact. This means that all superintelligences in the multiverse will merge into a single superintelligence devoted to maximizing all their values.

 But I still think Scott Alexander is the man.
