You can multiply by Graham's number and get a meaningful result. Try finding the expected return of four possible distributions: One in which you have epsilon chance of infinite negative utility and a 1-epsilon chance of doubleplusgood utility, one in which you have 95% chance of -infinity and 5% chance of plusgood, one in which you have epsilon chance of Graham's number negative utility and a 1-epsilon chance of doubleplusgood utility, and one where you have 100% chance of doubleplusungood utility.
Consider the case where epsilon is BB(Graham's number).
The first has an expected utility of -infinity, the second has the same value, but the third has an expected value of roughly doubleplusgood, despite having identical outcomes to the first one.
I recently published Mortal, a novella-length My Little Pony fanfiction meant to introduce anti-death concepts to an unfamiliar audience. Short description:
This is a character-driven melodrama. It's not particularly rationalist, but it's very, very transhumanist. Unlike, say, Friendship is Optimal, I wouldn't necessarily recommend this one to people who don't already know the source. It assumes familiarity with the characters and the world.
I am going to talk about how I put together the story and how people reacted to it. This will contain spoilers.
This line exists so you can break out of the automatic "read everything on the page" mode if you want to avoid the spoilers.
This story was structured as something of a bait-and-switch. I watched the reaction to a previous transhumanist horsefic (yes, there's more than one), and I was struck by how easily readers matched the explicitly anti-death narrative to the "immortality is a curse" trope. Rather than fight against this trend, I decided to work with it. The first act is meant to look like a story about learning to accept the inevitability of death. Starting in chapter 3, I break further and further away from that mold until the protagonists finally rebel against the status quo.
The first chapters got a lot of people invested who I suspect would've been turned off by a less familiar opening. Once I was into the third act, I stopped being subtle and used every trick in the book to make the pro-death characters look like the unreasonable ones. Judging by the comments, there's no shortage of readers who were angry at having their expectations flouted, but quite a few seem thoughtful, and some explicitly changed their mind on the subject.
