Okay, here is the problem, both in universe, and the real world.
In universe, the Enterprise is the result of two centuries of starflight development. Two centuries plus (Nomad reference? Of Independent logic. The implications are that Independent Logic capable computers aren't that much more capable than a human, and most likely less capable than a qualified human professional grade. In other words, a human professional has a higher level of understanding than a machine, with the typical example that a common human being greater than a common Independent Logic... quantitatively I am not sure just how much help is provided to the average individual human. But logic argues that it must be good enough to meet everyday common needs, otherwise, why use it for anything?
Let us say that before Duotronics, was around, the predecessor system, could be a helpful assistant to a Master of whatever ( Science, Law, medicine, philosophy, and so on), but inferior to the particular human. Duotronics took it up to Doctoral level.
Such that the Constitution class didn't precisely evolve as one would expect, but was going from one step to another. Why wasn't it evolved? Too few steps.
But why in universe was the Star Trek Phase II Enterprise the way that it was? Too few steps, remember?
Now here is the real problem: the Enterprise-D. Too radical for the number of steps. If your computers are barely capable, then how do you get to the Enterprise-D, so soon?
It isn't logical.
Now for the real world.
When Matt Jeffries, was working on the design of the Enterprise, he went through, it is said thousands of drawings. In other words actual evolution.
