"person" doesn't have a formal mathematical definition. "computer" does, and anything simulating our universe must be at least as powerful as a computer, since our universe contains computers. https://en.wikipedia.org/wiki/Turing_machine https://en.wikipedia.org/wiki/Turing_machine
- stcredzero 13y ago> "computer" does, and anything simulating our universe must be at least as powerful as a computer Yes, but that strikes me as about as useful as noting how many genes human beings have in common with yeast. (Useful in some contexts, but not all.)
- chriswarbo 13y agoNot at all. The point is not how amazing such a universe simulator must be, the point is that a universe simulator isn't amazing. The point of the Church-Turing thesis is that everything that ever was, is or will be; every supernova, every human mind, every intergalactic alien empire, every technology that ever can be, is no more complex than ENIAC (given sufficient memory).
