Too convenient? Really? It's grounded science, bud.

As it is, computers are reaching the point where we can make them any more smaller- meaning that we're making them as efficient and compact as possible. If we want to make REALLY powerful computing devices that will handle such complex things like quantum communications and FTL travel, then quantum superposition would be the next step. It's being studied right now- in a hundred years, this will have all undoubtedly become real.
