RE: starship-design: Ideas for the future
Kyle your supposition that computers and communications will be increasingly
important to spaceships (as well as to space travel in general) is well put.
C3 (Command, Control and Communications) are the backbone of any enterprise
(for the moment, I am neglecting Intelligence).
However your next points are slightly flawed:

Although the entanglement was indeed successfully demonstrated, no one has
been able to show a useful way of obtaining information from it. So far at
least, it is worthless as a communications device. Who knows what the future

This one is less problematic. You might possibly be able to store
information in a miniature black hole, but you can't retrieve it from one.
For the foreseeable future, quantum computers are the limit of what we can
The one thing you can say for certain about the future is that it will
probably be different from what you imagined - unless your name is Verne,
Clark or Asimov....I direct your attention to one of Asimov's short stories:
"Let There Be Light".
