Yes. My existence isn't so important that it just carries on, magically effecting the world while also being defined as having no observable effects. In a billion years, either I have observable effects, or I don't. If I don't, then talking about a me existing makes no sense. How would you even define me any more? Any test you would run for "Did there used to be a Michaelos over there a billion years ago?" would give the exact same results whether or not there ever was one.
So it makes no difference whether I torture you or not, because in a billion years no one will know?
I am an easily bored Omega-level being, and I want to play a game with you.
I am going to offer you two choices.
Choice 1: You spend the next thousand years in horrific torture, after which I restore your local universe to precisely the state it is in now (wiping your memory in the process), and hand you a box with a billion dollars in it.
Choice two: You spend the next thousand years in exquisite bliss, after which I restore your local universe to precisely the state it is in now (wiping your memory in the process), and hand you a box with an angry hornet's nest in it.
Which do you choose?
Now, you blink. I smile and inform you that you made your choice, and hand you your box. Which choice do you hope you made?
You object? Fine. Let's play another game.
I am going to offer you two choices.
Choice 1: I create a perfect simulation of you, and run it through a thousand simulated years of horrific torture (which will take my hypercomputer all of a billionth of a second to run), after which I delete the simulation and hand you a box with a billion dollars in it.
Choice 2: I create a perfect simulation of you, and run it through a thousand simulated years of exquisite bliss (which will take my hypercomputer all of a billionth of a second to run), after which I delete the simulation and hand you a box with an angry hornet's nest in it.
Which do you choose?
Now, I smile and inform you that I already made a perfect simulation of you and asked it that question. Which choice do you hope it made?
Let's expand on that. What if instead of creating one perfect simulation of you, I create 2^^^^3 perfect simulations of you? Which do you choose now?
What if instead of a thousand simulated years, I let the boxes run for 2^^^^3 simulated years each? Which do you choose now?
I have the box right here. Which do you hope you chose?
