There wouldn't be a problem if the programs were an inputless virtual
environment with conscious inhabitants. You could run it on any
general purpose computer with enough time and memory and the result
would be just the same, independent of the actual hardware. If you are
living in such a virtual reality now there is no way you could know
anything about the details of the hardware you are running on, or
notice any change if the hardware is changed.
