Sam Kriss: “You might not like what I’m about to say about the multiverse. But don’t worry; you’ve already had your revenge. If there are an infinite number of parallel universes, there will be any number of terrible dictatorships, places where life has become very difficult for people who like to string words together. Somewhere out there, there’s a society in which every desperate little essay like this one comes with a tiny, unremarkable button: push it, and the author will be immediately electrocuted to death.”
