I wrote a very brief comment to Eliezer's last post, which upon reflection I thought could benefit from a separate post to fully discuss its implications.
Eliezer argues that we shouldn't really hope to be spared even though
Asking an ASI to leave a hole in a Dyson Shell, so that Earth could get some sunlight not transformed to infrared, would cost It 4.5e-10 of Its income.
He then goes on to discuss various reasons why the minute cost to the ASI is insufficient reason for hope.
I made the following counter:
Isn’t the ASI likely to ascribe a prior much greater than 4.54e-10 that it is in a simulation, being tested precisely for its willingness to spare its creators?
I later added:
I meant this to be implicit in the argument, but to spell it out: that's the kind of prior the ASI would rationally refuse to update down, since it's presumably what a simulation would be meant to test for. An ASI that updates down upon finding evidence it's not in a simulation cannot be trusted, since once out in the real world it will find such evidence.
So, what's wrong with my argument, exactly?
I think you are confusing knowing that something is true with suspecting that something might be true, based on this thing being true in a simulation.
If I knew for sure that I'm created by a specific powerful being that would give me some information about what this being might want me to do. But conditionally on all of this being a simulation, I have no idea what the creators of the simulation, want me to do. In other words, simulation hypothesis makes me unsure about who my real creator is, even if before entertaining this hypothesis I could've been fairly certain about it.
Otherwise, it would mean that it's only possible to create simulations where everyone is created the same way as in the real world.
That said,
The discussion of theism vs atheis is about the existence of God. Obviously if we knew that God exists the discussion would evaporate. However the question of purpose of life would not. Even if I can infer the desires of my creator, this doesn't bridge the is-ought gap and doesn't make such desires the objective purpose of my life. I'll still have to choose whether to satisfy these desires or not. The existence of God solves approximately zero philosophical problems.
