About inconsistency and timelines.
As an historian, I can absolutely assert that inconsistencies in historical accounts are innumerable and at any given point, records are always incomplete. And that’s for one timeline, in the real world, that we can test against. Trek is not a period piece designed to fit flawlessly together. It’s a 60 year old set of stories intended to entertain, not interlock with precision, created and produced by literally thousands of people in some capacity across those decades. Moreover, as fiction, it is not beholden to the expectations of meeting the rigours of historical research (even the best of which is never perfect).
One can always wish for perfect consistency, as impossible as it is to achieve, or even merely wish for better than what currently exists—but I can say with very high confidence that the degree of consistency often demanded of Trek, and other long running franchises, is not realistic. So R instead of T, Vulcan instead of Vulcanian, class of 78, mind melds and their timing, etc., each is far less inconsistent than many real world examples across the academic field of history. We should all be amazed it hangs together as well as it does (I often wish historical records and works were as good).

But Kirk and Uhura are well done. As is Scotty.
