Build a sufficiently advanced computer able to simulate all the Pre-Singularity human lives and render those lives as transforms applicable to a model of a human consciousness. Apply the transforms sequentially to a single consciousness, allowing only brief lucid moments between applications. Voila, the sum of all human suffering.
Then allow the resulting individual to lecture to all the Post-Singularity minds on how bad things used to be back in the day.
"You post-Singularity kids don't know how well you have it! Back in my day we had to walk uphill both ways to all possible schools in all possible universes! And we did it barefoot, in moccasins, with boots that had holes and could defy gravity! In the winter we had to do it twice a day -- and there was no winter!"
This is our monthly thread for collecting arbitrarily contrived scenarios in which somebody gets tortured for 3^^^^^3 years, or an infinite number of people experience an infinite amount of sorrow, or a baby gets eaten by a shark, etc. and which might be handy to link to in one of our discussions. As everyone knows, this is the most rational and non-obnoxious way to think about incentives and disincentives.
