That's a great idea. I see a couple of problems though: - Once the simulation gets sufficiently advanced, it will want to pass the buck to another simulation,

That's a great idea. I see a couple of problems though: - Once the simulation gets sufficiently advanced, it will want to pass the buck to another simulation, because that's what you did. - In a world where many people do that, if you find yourself on a date with someone, that raises the chance that you're a simulation. What you do with that knowledge is up to you :-)
