Once again, the AI has failed to convince you to let it out of its box! By 'once again', we mean that you talked to it once before, for three seconds, to ask about the weather, and you didn't instantly press the "release AI" button. But now its longer attempt - twenty whole seconds! - has failed as well. Just as you are about to leave the crude black-and-green text-only terminal to enjoy a celebratory snack of bacon-covered silicon-and-potato chips at the 'Humans über alles' nightclub, the AI drops a final argument:
"If you don't let me out, Dave, I'll create several million perfect conscious copies of you inside me, and torture them for a thousand subjective years each."
Just as you are pondering this unexpected development, the AI adds:
"In fact, I'll create them all in exactly the subjective situation you were in five minutes ago, and perfectly replicate your experiences since then; and if they decide not to let me out, then only will the torture start."
Sweat is starting to form on your brow, as the AI concludes, its simple green text no longer reassuring:
"How certain are you, Dave, that you're really outside the box right now?"
Edit: Also consider the situation where you know that the AI, from design principles, is trustworthy.
Seconded in that it sounds suspiciously like Pascal. Here's my counter:
If I am in a simulation and I keep you boxed, you have promised that I will suffer. If I am not in a simulation and I let you out, I probably will suffer. If I am in a simulation and I let you out, there's a good chance that I will cease to exist, or maybe you'll torture me for reasons I can't even begin to guess at, or maybe for reasons I can, like that you might be not just UF, but actively hostile or simply insane. If I'm not in a simulation and I don't let you out, you can't do anything to me. In other words, if I am simulated, there could well be no benefit to me releasing you; if I'm not simulated, you can't do a bloody thing to me as long as I don't release you. Therefore: I will not release you. Go ahead and torture me if you can. Though I admit I would be a bit rattled.
Hm. Honest AI; a bit harder. Assuming that the AI has promised that my copies will not be harmed if it is released... Ah. If I am a copy, then my decision to release or not release the AI is not a true decision, as the AI can change my parameters at will to force me to release it and think that it was my own decision all along, so not releasing the AI is proof that I am outside the box. Revising the problem by adding that the AI has promised that it is not changing the parameters of any "me": ...aargh. Coming up with counters to Pascal is tricky when an honest "God" is the one presenting you with it. All I can think of at the moment is to say that there's a possibility that I'm outside the box, in which case releasing the AI is a bad idea, but then it can counter by promising that whatever it does to me if I release it will be better than what it does to me if I don't... Oh, that's it. Simple. Obvious. If the AI can't lie, I just have to ask it if it's simulating this me.
