Perhaps your real life is so rich you don't have time for another. Even so, the US Department of Defense (DOD) may already be creating a copy of you in an alternate reality to see how long you can go without food or water, or how you will respond to televised propaganda. The DOD is developing a parallel to Planet Earth, with billions of individual "nodes" to reflect every man, woman, and child this side of the dividing line between reality and AR. Called the Sentient World Simulation (SWS), it will be a "synthetic mirror of the real world with automated continuous calibration with respect to current real-world information", according to a concept paper for the project. "SWS provides an environment for testing Psychological Operations (PSYOP)," the paper reads, so that military leaders can "develop and test multiple courses of action to anticipate and shape behaviors of adversaries, neutrals, and partners".
"The idea is to generate alternative futures with outcomes based on interactions between multiple sides," said Purdue University professor Alok Chaturvedi, co-author of the SWS concept paper. (The Register)
