Posthumans? What? Since we're thinking in realms of "probabilities", what is the probability that the super-reality we are simulated in resembles our own reality? Why do we assume the agents that designed our reality are anything like us? Keeping in mind that we can't begin to imagine most of what is the reality around us (the "really big" or "really small"), what makes us think we can imagine what life of agents in a super-reality would be like? How broadly do we define "computer"? This article seems like a dumbed down version of stoned CS majors ramblings... bah.
