It's too early to tell fpr sure, but we can emulate any hardware and software that we want, so I doubt anything will really completely die. That was practically a plot point in one of my favorite books, A Deepness in the Sky by Vernor Vinge. Humanity has been travelling between the stars in slower-than-light ships for ten or twenty thousand years. A teenage prince from a medieval society with ancient legends of flying machines boards a starship and spends a few years learning math and engineering and programming. He learns to delve deep into the many layers of helpful interfaces and emulation, and even discovers that the clocks don't count from man's first moon landing, but from six months afterwards (which means that underneath it all they're running some variety or derivative of Unix). He finds bugs from practically before the dawn of time, and adds a few backdoors to the mess. A few thousand years (and a lot of coldsleep) later, he's old and broke, and joins a starship crew as Programmer Archaeologist Third Class. Other than that it's not very related to your question, but you should read it anyway.
