No I've never tried using such simulationist sympathetic magic myself, and since I still question the basic assumptions behind such mass-simulation in the first place, I have no intention of trying it in the future, either.

Ha! But are you saying that because you really never tried or because you tried and it worked? :p

However, about your thoughts on the whole mass-simluation affair: if we live in a faithful simulation and we discover we are living in it, then this raises the probability that even our ancestors found out that they were living in a simulation.

ETA: you could also try to outsmart your simulators by leaving uncorrelated notes about all your life, and producing false evidence about everything you do or that happens to you, so that future archaeologist will have a hard time reconstructing your life. That will either cause your death (due to the excessive complexity of your reconstruction) or they will need a reliable source of information... that yourself will have constructed!
