In the Trek universe, LCARS wasn't getting continuous UI updates because they would have advanced, culturally, to a point where they recognized that continuous UI updates are frustrating for users. They would have invested the time and research effort required to better understand the right kind of interface for the given devices, and then... just built that. And, sure, it probably would get updates from time to time, but nothing like the way we do things now.
Because the way we do things now is immature. It's driven often by individual developers' needs to leave their fingerprints on something, to be able to say, "this project is now MY project", to be able to use it as a portfolio item that helps them get a bigger paycheck in the future.
Likewise, Geordi was regularly shown to be making constant improvements to the ship's systems. If I remember right, some of his designs were picked up by Starfleet and integrated into other ships. He took risks, too, like experimental propulsion upgrades. But, each time, it was an upgrade in service of better meeting some present or future mission objective. Geordi might have rewritten some software modules in whatever counted as a "language" in that universe at some point, but if he had done so, he would have done extensive testing and tried very hard to do it in a way that wouldn't've disrupted ship operations, and he would only do so if it gained some kind of improvement that directly impacted the success or safety of the whole ship.
Really cool technology is a key component of the Trek universe, but Trek isn't about technology. It's about people. Technology is just a thing that's in the background, and, sometimes, becomes a part of the story -- when it impacts some people in the story.

Stories which focus on them as technology are nearly always boring. "Oh no the transporter broke... Yay we fixed it".
Not to be "that guy" but LCARS wasn't getting continuous UI updates because that would have cost the production team money and for TNG at least would have often required rebuilding physical sets. It does get updated between series because as part of setting the design language for that series.
And Geordi was shown constantly making improvements to the ship's systems because he had to be shown "doing engineer stuff."
Things just need to "look futuristic". The don't actually need to have practical function outside whatever narrative constraints are imposed in order to provide pace and tension to the story.
I forget who said it first, but "Warp is really the speed of plot".
It is for the audience to imagine that those printed transparencies back-lit with light bulbs behind coloured gel are the most intuitive, easy to use, precise user interfaces that the actors pretend that they are.
In the Trek universe, LCARS was continuously generating UI updates for each user, because AI coding had reached the point that it no longer needs specific direction, and it responds autonomously to needs the system itself identifies.
On the other hand, if the writers of Star Trek The Next Generation were writing the show now, rather than 35-40 years ago - and therefore had a more expansive understanding of computer technology and were writing for an audience that could be relied upon to understand computers better than was actually the case - maybe there would've been more episodes involving dealing with the details of Future Sci-Fi Computer Systems in ways a programmer today might find recognizable.
Heck, maybe this is in fact the case for the recently-written episodes of Star Trek coming out in the past few years (that seem to be much less popular than TNG, probably because the entire media environment around broadcast television has changed drastically since TNG was made). Someone who writes for television today is more likely to have had the experience of taking a Python class in middle school than anyone writing for television decades ago (before Python existed), and maybe something of that experience might make it into an episode of television sci-fi.
As an additional point, my recollection is that the LCARS interface did in fact look slightly different over time - in early TNG seasons it was more orange-y, and in later seasons/Voyager/the TNG movies it generally had more of a purple tinge. Maybe we can attribute this in-universe to a Federation-wide UX redesign (imagine throwing in a scene where Barclay and La Forge are walking down a corridor having a friendly argument about whether the new redesign is better or worse immediately before a Red Alert that starts the main plot of the episode!). From a television production standpoint, we can attribute this to things like "the set designers were actually trying to suggest the passage of time and technology changing in the context of the show", or "the set designers wanted to have fun making a new thing" or "over the period of time that the 80s/90s incarnations of Star Trek were being made, television VFX technology itself was advancing rapidly and people wanted to try out new things that were not previously possible" - all of which have implications for real-world technology as well as fake television sci-fi technology.
Now, this is really because LCARS is "Stage Direction: Riker hits some buttons and stuff happens".
The people we saw on screen most of the time also held important positions on the ship (especially the bridge, or engineering) and you can't expect them to just waste significant chunks of time.
Also, don't forget that these people actually like their jobs. They got there because they sincerely wanted to, out of personal interest and drive, and not because of societal pressures like in our present world. They already figured out universal basic income and are living in an advanced self-sufficient society, so they don't even need a job to earn money or live a decent life - these people are doing their jobs because of their pure, raw passion for that field.
Complex tasks are done vibe coding style, like La Forge vibe video editing a recording to find an alien: https://www.youtube.com/watch?v=4Faiu360W7Q
I do wonder if conversational interfaces will put an end to our GUI churn eventually...
Conversly recent versions have taken the view of foregrounding tech aidied with flashy CGI to handwave through a lot.Basically using it as a plot device when the writing is weak.
AKA resume-driven development. I personally know several people working on LLM products, where in private they admit they think LLMs are scams
That's probably part of it. But the larger part is that new Star Trek is very poorly written, so why is anyone going to bother watching it?
Similarly in Stat Wars with droids: Obi-Wan is right, droids can't think and deserve no real moral consideration because they're just advanced language models in bodies (C3PO insisting on proper protocol because he's a protocol droid is the engineering attempt to keep the LLM on track).
It might be nice way for making complex, one off tasks by personnel unfamiliar with all the features of the system, but for fast day to day stuff, button per function will always be a king.
Yes, although users also judge updates by what is apparent. Imagine if OS UIs didn’t change and you had to pay for new versions. So I’m sure UI updates are also partly motivated by a desire to signal improvements.
In truth, that was due to having a fixed sight-line and focal distance to the camera so any post-production LCARS effects could be matched-moved to the action and any possible alternative lighting conditions. Offhand, I can't think of any explicit digital match-moving shots, but I'm certain that's the reason.
As pointed out in that infamous Red Letter Media video, all the screens on the bridge ended up casting too much glare so they very blatantly used gaffer tape on them https://www.youtube.com/watch?v=yzJqarYU5Io . :)
The less obvious answer is how to make it work. That is a hard problem.
And the challenge is how to make it work ethically, especially given where Late Capitalism has ended up.
Otherwise we won't turn into Star Fleet, we'll turn into the Borg.
