Yes, it is. Entropy increases over time. Things break.
If they are designed to NOT break, chances are that things will survive for ridiculously large amounts of time - which we can already do if we put some effort into it... its mainly not done on a commercial level due to 'cost efficiency'.
Also, ever heard of self repair and self-maintenance? Both existed in 23rd and 24th century just not used to full potential.
Even during the 24th Century, Bajor was still in the process of rebuilding from the Occupation after obtaining multiple industrial replicators. Replicators are not actually a cure-all.
Bajor only got 1 industrial replicator from UFP and it was deemed ready to join the UFP in under 5 years. That was a planet that underwent an occupation for 50 years and was virtually STRIPPED of its resources.
Quite a remarkable and fast recovery with just 1 industrial replicator.
After the Burn, 38 remaining UFP member planets... all with INTACT highly advanced technology (replicators and programmable matter - not to mention starbases, outposts, colonies, etc.) was more than enough to recover (especially during 125 years).
Sure, SF/UFP would have cautiously approached Warp travel after the Burn, but recovery with that kind of 'base' of technology and planetary resources should have been done in the first decade or two after the Burn... and re-established long range sensors and communications.
The way Disco presented the situation was as if the Burn happened a year or two after it arrived.
Seriously... over 100 years and 0 progress in recovery with what they had?
Utterly moronic and bad storytelling.
SF/UFP HQ could have easily linked all the ships stationed at HQ to continuously R&D new technologies and science... the remaining 38 member planets could have done the same.
The notion you'd experience ANY kind of regression is just ridiculous... and we know this wasn't the case because things were in general presented as being FAR more advanced compared to Disco's original 23rd century tech (sans the Spore Drive).
Sure, until the day comes when something damages the information stored inside the emitter and suddenly its hologram can't access the files necessary to repair itself.
Such as what?
The EMH backup module kept the EMH intact for 700 years and was inferred the thing can keep him in there for another few eons... plus it survived passage of time while being supposedly buried under rubble (which survived after how much time of infighting?).
We already are designing storage that can last thousands of years... millions even.
To think UFP wouldn't be able to do such a thing (or even better) is quite frankly preposterous.
Honestly that's about the best possible scenario, since Data's head was probably shielded by the rock from the normal radiation exposure everything on the surface experiences.
And yet, it survived hundreds of years of passage of time with all sorts of critters and earthquakes.
Interesting.
"The Titanic can't sink due to water-tight compartments!"
If a Federation engineer were to actually make such a claim, the word for this would be "hubris."
The original ship builders of the Titanic insist they never made the claim the ship was unsinkable.
That was a myth born out of people's mis-interpretations of articles in the Irish shibpbuilding magazines.
Speaking of which, I'm reminded of transverse bulkheads... Paris created them during year of hell to increase the amount of protection the crew would get in case of wide-scale breaches (which actually worked)... and if I recall, VOY was badly beaten and still managed to bring the fight to Annorax and Janeway managed to ram VOY into the time ship (after VOY received a dose of pounding from the time ship's conventional weapons).
Point is, the bulkeheads were meant to INCREASE crew's odds of surviving catastrophic breaches... and they did just that.
Paris never made the claim the ship would be indestructible.
Nothing canonical ever indicated the Phoenix functioned without dilithium.
And nothing canonical states otherwise.
But we do have a pointer.
From VOY, Chakotay stated on-screen that subspace technology wasn't invented until around 2196 (100 years or so after their sidetrack in the late 20th century 'Future's End')... to me, this would suggest that dilithium hadn't started being in use until AFTER subspace technology was developed.
First Contact Movie had Geordi saying inside the Phoenix to switch on the Warp core... which would at least suggest use of M/AM... but even if antimatter was used in that Warp core (whatever it was the Pheonix used at the time), it doesn't mean Dilithium was used.
Also, we know that Humans and most other Trek species used antimatter for the most part to generate enough power for Warp... but nothing indicates that's the ONLY reliable way of doing so.
Furthermore, Discovery has a nasty habit confusing power generation and FTL propulsion thinking they are both one and the same - they are not.
The only reference I can find to this is from a goddamn computer readout, which was not confirmed in dialogue. Personally I think info from most computer readouts is about as canonical as the giant hamster in a wheel aboard the Enterprise-D. But even then, nothing there precludes the necessity of dilithium to regulate the energy when it is transferred to warp coils.
If its on a computer readout seen on the TV show (which are considered canonical)... its pretty much part of canon - second best compared to on-screen dialogue itself.
Every version of FTL travel ST has canonically shown so far requires dilithium, and the fact that the Burn is described as having a universally damaging effect upon all FTL-capable civilizations is the final canonical proof of that.
Incorrect.
The Caretaker flung ships from across the galaxy using a Tetryon reactor - which the VOY crew had scans of, and even managed to help repair one in Season 6 (which begs the question, if they had 0 information on the thing, how could they help repair one?).
The fake USS Dauntless (Quantum Slipstream V1) was never mentioned that it had dilithium and Paris even mentioned its main core is NOT antimatter.
Dilithium and M/AM are 'commonly' used to achieve Warp and other forms of FTL travel in Star Trek... but they're NOT the only way of doing so.
The Borg have unknown means of power generation, and are never stated to use Dilithium and M/AM.
The UFP was researching different ways of generating Warp and new power sources in the 24th century itself during TNG run.
The Romulans also used a Forced Quantum Singularity as a power source... no mention of Dilithium usage there either.
It's very 'convenient' for Disco to handwave everything away... and I find that utterly lazy and stupid.
