Okay, so a lot of people have said that the NX class is a lousy design because it is a copy of the Akira class. Or they've said that the Akira class is a bad design because it is so similar to a ship design that Starfleet used two centuries earlier.
Personally, I never found either of those arguments to be convincing. While they are very similar, why should Starfleet have a 24th century ship that is based on a 22nd century design? The Galaxy class is likewise clearly descended from the Daedalus class.
What are your thoughts?
