Re: It costs more to write new software than to maintain old hardware
An important consideration is that legacy software will usually work just as effectively on a simulation of an old computer as on the computer itself
But for a critical application like the nuke one being discussed, I guess you'd need guarantees about the reliability of the underlying emulator. Last thing you want is for the emulator to glitch and for the programming running on it to thing that the bDeclareWarOnChina register has been set to 1.
