Hello, I have a few questions regarding computational power. In the far off future, I imagine creating a realistic virtual reality, a cybernated solar system composed of a sun like star and numerous habitable planets and moons with the same complexity of life on Earth. For this solar system I would like to create 100,000 computed humans in it. All of them would have consciousness. And perhaps the ability to even download my own consciousness into these virtual worlds. But there are issues with this concept, the first one is no one knows exactly why we are conscious beings, that is currently being researched, the second being is processing power, all of this simulation would require huge levels of computation power. IBM researchers estimate that even just one human brain considering it's complexity would compute at 36.8 petaflops, or 36.8 quadrillion of data per sec. What is the theoretical max limit of computing power for a computer one kilogram? Seth Lloyd calculates an upper theoretical bound for a 1 kg computer of 5*10^50 logical operations per second carried out on ~10^31 bits. Are his calculations accurate to what the true upper limit is? Sources would obviously be greatly encouraged.
