If we live in a simulated reality computed by means of digital physics by another level of reality, which may be the primary reality of our computronium based AI mind children in a future time, then we live in a universe with a conceptually simple, and scientifically sound, practical engineering mechanism for our own resurrection, by copying sentient beings living in the sumulated reality (us) to another simulated reality (or even the primary reality itself). Of course we probably cannot even imagine the motivations of computronium superintelligences, but it seems plausible that they would copy and store interesting patterns to run them again. At least, this is what CA and Alife researchers do today. This is illustrated by the short movie CA Resurrection, which I just made with a Game of Life program. The protagonist pattern is doomed to certain death by interaction with an environment that, except in very carefully controlled conditions, is very unfriendly to the stability of patterns (sounds familiar?), but is copied before death and restored to life in a friendlier environment.http://giulioprisco.blogspot.com/2008/10/ctrl-alt-r-another-life.html Less
