How does the speed of light limitation make sense for any reason but computational tractability? (locality=>parallelizable). (Not saying we're a simulation, there are other scenarios where the universe "runs" on some underlying "hardware".)
This kind of a circular argument, though, unless computation requires locality even in a universe without locality. Otherwise it's just saying that program locality implies hardware locality, which is just hopping to the next turtle.
