^That's exactly my point -- that the details are matters of artistic interpretation and it's the overall story that matters most. It shouldn't be necessary to tell a story justifying why futuristic 23rd-century technology looks like it was built with 1960s switches and dials, because it shouldn't be necessary to pretend that's actually, literally how it looks in-universe.
Has anyone considered this is what state-of-the-art 23rd century technology actually looks like? It isn't 1960s, it's 2260. It may look primitive to us 21st century people but maybe the design ethics of the future are just different
. Starfleet equipment is built to be practical and good looking. This is what looks cool to 23rd century Starfleet.
Remember, when a few years ago, people started running around with awful 80s, 70s and finally 60s styles? Male hairstyles never recovered from that even today.
And remember how advanced everything from the 23C looked compared to the 22C in In A Mirror, Darkly
Furthermore, 25th century Starfleet is flying around in NX-class replicas and the centuries old D'kyr
-class - they still have the old look but their technology is state-of-the-art. It's just old, venerated design.
More examples: 26C Starfleet was a visual callback to the 23C in the abortive Star Trek: Final Frontier
series and the 29C mirrored 24C design guidelines.
DS9 brought up the two Klingon situation and that led to Enterprise trying to explain it in a Small Universe Syndrome story that not only had Humans responsible for the change but connected it to Khan via the Augments. Did we really need 4 hours of Trek devoted, at least in part, to explaining away something that didn't really need an explanation? Trek fans are smart people. We don't need everything spelled out for us.
Huh? If we Trekkies didn't need everything spelled out, why would we even have a thread about retconning? Personally, I love to see inconsistencies explained and the ENT double feature killed one of the most glaring. Part of the flavour of having an ongoing continuity is that problems get explained away sooner or later.
