Inspiration came from Against the Linear Utility Hypothesis and the Leverage Penalty

Place a value on the utility of a utopia with 1 human, let's call this X.

Place a value on the negutility of all of humanity going extinct. Let's call this Z.

Decide if your utility function is linear in number of lives saved.

Place a value on the utility of say ${10}^{100}$ humans achieving a perfect utopia. Call this K.

Omega offers you a bet. This bet has a 50% chance of humanity reaching a Kardashev type V civilisation (colonising the multiverse) and a perfect utopia, and a 50% chance of human extinction this instant.

Omega is an omnipotent entity that always tells the truth, you know (and believe this), etc.

Do you accept the bet?

What about 1:3 odds?
What about 3:1 odds?
What is the highest probability of extinction at which you would accept Omega's offer?

What does this say about your utility function?
