What if the brain of the person you most care about were scanned and the entirety of that person's mind and utility function at this moment were printed out on paper, and then several more "clock ticks" of their mind as its states changed exactly as they would if the person were being horribly tortured were printed out as well, into a gigantic book? And then the book were flipped through, over and over again. Fl-l-l-l-liiiiip! Fl-l-l-l-liiiiip!
Would this count as simulated torture? If so, would you care about stopping it, or is it different from computer-simulated torture?
Consider a slightly different thought experiment. Suppose some government, as it tortured a prisoner, took a brain scanner and took a series of, say, 200 pictures of that person's brain, spaced, one second apart. Those pictures are then printed out, and they can be "flipped through" in the manner you describe. But suppose instead that you simply took the pictures, stacked them, and then put them in a box off in a warehouse somewhere. Does that count as simulated torture? Even better, what if you took the entire box in an airplane, and scattered the pictures out the window so that the wind blew them all over the world. What's the difference here?
While flipping through the printouts creates the illusion of seeing something happen, it is not a simulation. When you watch a movie on DVD, you are not watching some alternate universe where the movie's subject is actually occurring, and the photons are being transmitted into your own universe to be projected out of your TV. It's an optical illusion. Nothing about "flipping" the printouts does anything special, other than create an illusion within your own brain. You are not going to be able to absorb all the data on the sheet anyway (at least not at regular flipping speeds) so there is no chance of your own brain being used as the computing substrate.
Rather, the actual simulated torture in this scenario would be the actual calculations to generate the printouts. That does count as torture, and I would pay to stop it. But once the calculations have been done, it doesn't matter how many pieces of paper come out of the printer.
I think I agree with all but the last sentence. But I definitely would not feel comfortable creating more physical objects that might exhibit probabilistic causality if you knew their source, and that describe perfectly a person feeling torture.
I think I could justify drawing a line between this and the process of flipping, despite the flips creating patterns of photons, because the fact that papers in a box have different patterns of ink on them should have similar effects on the world around them.
