Do we exist?
Since the 1970s the speed at which computers process information has been exponentially increasing. Along with that, the quality of the images that they are able to produce has been dramatically improving. Also, we are on the brink of being able to create human like simulations who are able to think, feel and respond as people would in real life and that might not actually be aware that they are simply simulations. This potential throws up a fascinating question. If civilisations of the future can build sophisticated virtual replications of the past, and not just one version, but an infinite number of possible pasts, can we be so sure that we are actually real and not part of a sophisticated simulation from the future? Some scientists believe that it’s almost certain that most of us are actually part of a simulation from the future. In other words, we aren’t real at all.
