Reminds me of the story I heard back in 2000 that by 2090 computer chips will have to generate small nuclear explosions to get the necessary procssing power required for Moore's Law (by then, I'm sure, history will have changes so that it was Sir Roger Moore who made the original statement :-D ).
Question is, why bother? Soon you will have all the power you need, like a car doesn't need unlimited horsepower, and you only need a few hundred nuclear bombs to destroy a planet, so why make more?
You'd have to have some INCREDIBLY inefficient programs to require processing power by then.
Actually, Windows 2090 (Oh God, I hope not) would be just the application. It would still run slowly and crash...
