I've counted at least three civilization-shattering technologies in Star Trek which were simply thrown in, without consideration for the long-term, for reasons of budget and convenience, but largely to maintain the Sailing Ship, Days of Yore set of metaphors.

Transporters: Originally designed to save on tedious shuttle launches and landings and, most importantly, footage, these would utterly rewrite medicine, aging, manufacturing, and so on. Notice in many high adventure films, the dinghy, the shuttle's ancestor, is often ignored.

Artificial Gravity/Inertial Dampeners: We want our ship to be under our boots, and occasionally slosh around when we are enduring space weather. Casual mastery of the force of gravity so we can have an ion storm to knock us about.

Faster-Than-Light: Aside from that messy causality business, real FTL would make the concept of territories quite fuzzy. Sure, you could draw lines on your star charts, but given that someone could zip a few dozen light years in and attack your capitol planet, it's just not the same.

I could go on and on about this, but a lot of this space opera harkens back to a time when governments would just have to trust that some captain or governor was a reasonable person to have in charge because messages back and forth would take so very long.

I think there's a fourth, which in my opinion is even more world shattering than the others -- the replicator. It often was shown as a novelty device to make food or warm beverages, but the ability to convert energy into any needed material would instantly transform the world into a post-scarcity, post-economic future. What would you even use as currency when everyone has personal money making machines? I've seen some people be skeptical towards the utopian future of Trek, and I understand that a bit as the show puts great emphasis on the warp drive, but I think the replicator is quietly the greatest invention they depict (and unlike warp drive, at least vaguely possible).

[jimbokun]

Star Trek is very explicitly a post-scarcity society. There was an episode of Next Generation where they revive some Earthlings who had successfully frozen themselves in the 20th century.

One was a businessman who was excited to see how much the stock portfolio he had put together as a long term trust had fared. Picard had to gently explain to him wealth and money were no longer a thing.

[SenHeng]

Last episode of the first season.

Of course the Picard series itself then thoroughly destroys that thought by going on and on about money.

[hef19898]

In all fairness, between that episode and Picard, the Federation had extensive contact with the Ferengi.

It often was shown as a novelty device to make food or warm beverages, but the ability to convert energy into any needed material would instantly transform the world into a post-scarcity, post-economic future.

IIRC, in Star Trek, the replicator does not convert energy into needed material: it simply reorganizes existing molecules into a new form.

So, for instance, you can't use it to make yourself a bunch of gold: you could use it to convert a bunch of gold jewelry into gold bars, or vice-versa, but you would need some actual gold. It won't convert lead into gold. I think I heard or read somewhere in the lore (maybe non-canon) that the food replicators needed supplies of biochemical ingredients to use for making food. They could get that from various places, including breaking down the waste of the crewmembers, but they couldn't just conjure food out of nothing using pure energy.

[SenHeng]

Replicator technology often comes up in episodes involving trading with a less advanced civilisation, and often mentions how the Federation/Star Fleet is not willing to share that technology because it’s too game breaking.

And that unlimited energy has led them to a post scarcity, post money utopia, though that scenario seems to have been withdrawn a little in Picard.

[hef19898]

The one thing, despite all other things I critique regarding Star Trek I still like it, that drives me crazy is how the Federation treats first contacts, from their prime directive to diplomacy in general. The whole concept is so fucked up. And every other power should be so quick in capitalizing on this: Those people won't share their miracle tech with you, we will. For a price. Kind of like what China is doing in Africa.

Edit: Why would someone, say the Romulans, do that? Well, Starfleet doesn't establish contact, or invite a planet, because of some on going war or a non-unified government or no FTL tech. The Romulans step in, side with one party. They provide technology and weapons, they unite the planet as an "ally" or theirs. And now they have a new planet and systek to exploit, to use a base. Legally, and even better the Federation canot intervene. Rinse and repeat everytime Starfleet side steps a planet in a strategically important position. Do so over a couple of decades. You see were I am going, right?

[ralfd]

In the original series there is an episode where Klingons provide flintlock guns to a tribe on a stone age planet. Kirk wants to provide the other tribes with guns too and argues with McCoy about keeping the balance of power:

[SenHeng]

Totally agree. For a warrior race, the Klingons sure don’t seem to do that much conquering when it would make so much in-world sense for them to be Romans-in-space.

They really seemed to make every race encountered to be a relatively peaceful semi-utopian culture.

[hef19898]

If you extrapolate Klingon martial culture and capabilities from their traditional weapon, the Bath'let, this in-universe behaviour makes perfect sense!

Edit: For some reason, every non-FTL civization Star Trek just seems to be ignored by everyone. Heck, even the Dominion ignored them in their empire building...

That's authors so: In the Star Wars Legends EU there are the Ssi'ruuk. A species from the edge of the universe harvesting other lifeforms, litterally, for power generation. Throughout the books about them, the fact they could go on a spree of exterminating each and every primitive species they encounter is never mentioned or even hinted at. Nor is the fact, that with a bare 6 systems under their control, and inferior ships and tech, they should be one punitive expedition away from extinction themselves.

[actionfromafar]

The Klingons are extremely big on honor, though. I think that taken at face value, can be just as self-limiting as a prime directory. Subjugating an inferior planet just for resources doesn't seem honorable at all and in my mind I can play a scene of klingons ridiculing someone suggesting it.

[hef19898]

Isn't the Klingon way of conquering a world something like killong all government officials and installing an imperial overseer? If I remember that DS9 episode correctly.

[coryrc]

Gold-pressed latinum, obviously, as it can't be replicated.

[crooked-v]

Also hand-woven traditional scarves, to reference a certain podcast. Sure, you can replicate them, but then it's not genuine anymore.

More seriously, the basic answer for the Federation in particular would be "amounts of energy". Voyager uses exactly that, with minor but consistent references to 'replicator rations' because they're limiting the total energy usage of the ship.

[Ekaros]

What fails me with TNG is that why would anyone do any of the jobs that require hard boring labour anymore? Like mining dilithium, or other stuff that isn't easy to replicate.

Are they all some starfleet officers toiling for decades on off-chance that one day they might get job on a vessel? The ages of people on show don't present that...

The whole post-scarity kinda really breaks down when you start to look at edges. As society would not be effectively be able to keep up the production at least not as shown in shows...

[shiroiushi]

The 60s version of Star Trek just wasn't very well thought out, I think.

[vladms]

I see scarcity more related to primary resources (ex: energy, raw materials, machines) and for normal life purposes. They obviously have some way to decide who does what (not everybody is captain), but the impact of not being captain on what you eat, what you dress, what furniture you have is much less than today.

Now, if you want an Enterprise like personal spaceship, you probably are much better of being part of the Q continuum than the human race, scarcity wise.

[at_a_remove]

Oh, I lump the replicator in with the transporter. I can see the replicator as an ancestor of the transporter.

[thaumasiotes]

> What would you even use as currency when everyone has personal money making machines?

Cumals.

You can give everyone as much food as they want (and we already do!), but you can't eliminate scarcity.

[rhaps0dy]

What is a cumal?

[thaumasiotes]

Wikipedia would have told you.

A cumal is the unit in which medieval Irish monetary values are denominated. It is also the medieval Irish term for a female slave; the unit is notionally equal to the value of one such.

The point of answering the question in a historical currency is to emphasize that this question is easy to answer by simply thinking "what have been some well-known historical currencies?"

People trade in materials, tools, food, livestock, and women.

I'm more interested in how it would rewrite the rules of war. If you can transport a nuke (or even a strike team) directly into your enemy's headquarters, wars end faster with less widespread destruction.

Until you develop no-transport fields but now you've just created massive dead zones which - in themselves - highlight key points of interest to investigate and/or target.

Then you have to deploy LARGE scale (think city wide or bigger) no-transport fields or lots of smaller fields to obfuscate the high value targets.

But regardless, you still need normal shields because teleporting a nuke just outside the zone and letting it drop in is just as effective.

And all of that still ignores conservation of mass.. the physical material has to come from somewhere.

[crooked-v]

> the physical material has to come from somewhere

Extended canon Star Trek has references to both (a) feedstock material storage, with big blocks or tanks of elementally pure materials that get shaved off and recombobulated as necessary by the replicators, and (b) synthesis of elements from pure energy on demand, though usually with the preference of the first method over the second because it's far, far less demanding on all the systems involved to just move atoms around.

[caseysoftware]

That works well if you're going TO a transporter pad.

It doesn't work when they use a transporter to go to a desolate planet.

[mnw21cam]

Schlock Mercenary https://www.schlockmercenary.com/ dealt with this particular theme quite thoroughly. One of the protagonists invents a "Teraport", and promptly a "Teraport Area Denial" is invented to protect against it. Recommended read, though the archive is huge.

[jimbokun]

In a Star Trek novel, where bad guys take over the bridge of the Enterprise, someone in the crew repurposes a mini transporter that’s part of a game, to transport explosives into the parts of the ship controlled by the enemy as a way to fight back.

I thought that was a clever use of transporter tech.

[hef19898]

With the federation transportes, as depicted throughout the series, the impact is limited. Easy to block, unreliable. They are used so, all the time, for boarding actions.

Star Trek avoids this one by just completely ignoring the lightspeed barrier with handwavy "subspace" technobabble. They can communicate, detect, and track objects moving FTL with as much (or more) ease as done with radio tracking slow moving objects today.

[at_a_remove]

If you can get from A to B faster than a photon in a vacuum could, I'm counting it as FTL.

They've been really inconsistent about it. For a while, communicating through subspace was not quite as long as travel, but it was still a non-zero amount of time. Now, communication seems to be via ansible, and the less said about the wildly varying rates of travel, the better.

[SenHeng]

And yet, we have something like the Picard Manoeuvre that uses FTL to make it look like you have 2 or more ships in a single location. So they acknowledge that FTL is reality breaking, then just hand wave it away.

[Izkata]

Several episodes mention subspace relay stations, and between how communication seems to jump between real-time and waiting hours or more for a reply (I don't recall any minutes-long delays), I have a suspicion the unwritten rule is subspace communication has some sort of speed decay. Like it actually slows down the further it has to go, instead of going at the same speed but weaker, and subspace relay stations intercept the message and re-send it at top speed. More advanced technology in the later-set series could also then just send it faster than in the prequel series, explaining how they communicate over larger distances even though it's supposed to both be subspace communication.

[smogcutter]

I think the unwritten rule is that subspace communication takes precisely as long as the plot requires it to. (Especially in the more modern series)

[hef19898]

Star Trek is an extreme case of the plot driving the tech, and not the other way round. They manage to pull it off, most of the time, using ingenious Starfleet engineering and technobabble. For some reason, with Star Trek it works most of the time.

[mrec]

> Artificial Gravity/Inertial Dampeners

Surely this one was much more about those "reasons of budget and convenience"? Star Trek couldn't afford non-styrofoam rocks, I can't see them stretching to filming all bridge scenes on the Vomit Comet or building a 2001-style rotational set.

[amanaplanacanal]

One thing that struck me about TNG was how many plots were about Data and whether he should be considered alive, and what rights he should have, and absolutely no thought was given to the AIs in the holodeck.

[hef19898]

They did put Moriarity in his own holo reality. Quite cruel after all. Not sure ehat happened to him, I didn't watch the last season of Picard.

Also, the holodeck: Not only can the ship computers run multiple, basically self-aware General AI characters in parallel, it can also extent space beyond the confines of the decks physical dimensions. Pretty amazing tech, no idea why they don't use it to build the interior of all their ships, after all it also has superior environmental controls.

[Terr_]

That makes me think of the "teraport" invention from Schlock Mercenary, which is basically faster than light teleportation powered by a very small/evenly-spread amount of mass-to-energy conversion of whatever you're sending. (So basically three magics rolled into one.)

Large portions of the web comic are involved with how it completely rewrites the rules of politics and war, with and without review techniques designed to create interdiction zones.

[crooked-v]

I think that last part about FTL is taken more into account in the stories than you've considered. 'A Borg ship moving super fast suddenly showed up Federation core territory' is the driving conceit behind "Best of Both Worlds" and Star Trek: First Contact, FTL travel is the main technobabble allowing for surprise appearances of Romulan/Klingon/Ferengi ships in unexpected places in a number of episodes, and there are whole arcs in DS9 about the impact of the Gamma Quadrant wormhole and how it's abruptly connected two politically opposed parts of the galaxy.

[readyplayernull]

You can apply Disney's Star Wars logic to Star Trek and get an abominable time traveling FTL space ram that can destroy anything.
