We Will Use Manual Labor in the Future
aka: We Will Use Manual Labour In The Future
: As long as I get to keep my slaves. Bobby Crichton
: They're servants. They get paid. You don't own them. Rygel
: What? You're kidding. They come running when I call. Bobby
: The government wants you to feel at home. Rygel
: Then give me slaves.
Common in Science Fiction
, especially in Days of Future Past
, but also in Space Opera
, Wagon Train to the Stars
, and many other subgenres.
While the Cool Starship
of the series has fully automated food dispensers, and artificial intelligence
are realities, indentured servitude
and slavery of sapient beings is still widespread, and the most common slave occupation by far in The Future
(TM) is the lowly miner. Why mining? Because cave sets are cheap and easily redressed to represent different planets. However, we have to ask ourselves why such technologically advanced civilizations (presumably capable of building automated robot mines) choose to be so dependent on manual labour as to indenture or enslave thousands, even millions of sapient beings instead of applying technological solutions which are cheaper, stronger, more efficient, never get tired, more humane and less rebellious.
Sometimes the trope is justified by slaves or servants symbolizing social prestige, but in societies that are supposed to the technological near-equivalent of The Federation
or whatever outfit the heroes belong to, it comes as a bit surprising that interstellar polities so frequently appear dependent on menial and dangerous labour conditions with No OSHA Compliance
— and if they represent social prestige, why aren't they on display, as servants, maids, entertainers or sex slaves? Items of Conspicuous Consumption
aren't conspicuous if they are hidden away in a mine.
For what it's worth, there are some
benefits to slavery which could explain its use in a futuristic setting. There are some jobs (namely skilled, management and service work) which are just too complex for any currently envisioned mechanical technology to do without some human assistance. What makes this trope appear blatant and unable to suspend disbelief is that futuristic slavery rarely involves these environments, but rather dangerous hard labour such as mining, repetitive industrial work and space construction work. In these environments, slaves are way too soft and inconvenient to provide for because of the biological fact that they get exhausted and need to sleep (and in Sci Fi space labour you have to invest in highly expensive and complex life-support biospheres for every single slave, defeating the purpose of cheap in the first place), and they also have much more dangerous intelligence and machinery at their disposal. A disgruntled slave who's a mad scientist, MacGyver
-style improviser or C4 expert (or even one with just a pickaxe) is substantially more dangerous than one who works primarily with a hoe (not that you should write the latter guys off if you've got them in a pinch either — isn't that right, oppressors of the peasant caste in the ancient Far East?)
Part of the reason for this is that the evil being portrayed usually isn't the slavery itself, but the emphasis on punishment which the workers must endure. Many "The Gulag In Space
" examples are more about punishment than economic efficiency. In Sci Fi, you can identify The Empire
or any other villainous dystopia
through their use of Space Gulags
. In modern-day society, we have machines that are quite capable of automatically pressing license plates for free, but prisoners are the iconic way to do it.
This trope can potentially be justified for the same reason many industrial processes that could be automated are not. The time, cost, maintenance, and effort for completely automated systems can quite often be far in excess of what skilled labour can have. Automated systems often have a fairly limited lifespan, and the cost of building, maintaining, and replacement is occasionally ludicrously high, thus slave labour or labour that borders on slavery is used in lieu of automation because it's often actually cheaper provided the workers are from a poor country populated by species with a higher fertility rate and physical fortitude but much lower average IQ and life support costs than the country their masters or employers are from.
If the manual workers are not slaves but the normal population of a civilisation, a good reason for it is simply ethics. There are very few places there a human is mandatory to do the work. If too much is automated, most people are unemployed. This is actually a problem in many countries in the present (and even in the past two centuries) and a big reason why many people oppose industrialisation.
In addition, the amount of effort to build certain types of quality control is either not possible, absurdly difficult, or downright dangerous
. Occupiers may also use the local population instead of slaughtering them, in the hope that the workers' presence will deter
an all-out counter attack. Another common and logical way to justify the use of slaves is through presenting the history and dangers of A.I. Is a Crapshoot
, the reason why future civilizations want to avoid automation. A rogue AI can hijack automated systems with impunity, but individuals are easier to identify and kill when they get too loud.
Thus, this trope isn't about future slavery; it's more about any instances about using manual labour even though people in the series already have something that would be quicker, easier, more efficient, and/or overall better. A common yet rarely understood example is ubiquitous presence of characters upon ships capable of Faster-Than-Light Travel
- why stock and crew a starship when one can simply send an automated probe
? Because it's hard to tell entertaining stories about automated probes
. This is a big reason why Real Life space development holds few people's interest.
As well, beware of Technology Levels
; just because a civilization can travel in space doesn't mean
they actually have
servitor robots. But the series that have already shown automation yet refuse to use it in the obvious places don't have any excuse. This is perhaps the ultimate extension of Schizo Tech
. Compare with I Want My Jet Pack

Anime and Manga
- Similar to Alien Nation the Dears of Dears are a race of slaves who crashland on Earth that possess a good amount of technology for being a slave ship. However unlike Alien Nation they're genetically altered to NEED to be slaves. Depriving them of their built in desire to be slaves causes a lot of friction between them and their hosts (currently humans). May be justified in that Ren is genetically programmed to have sex with her master as soon as she detects he's 'in the mood' (they're also blindingly gorgeous) so much of the reason for their creation could be sexual.
- In an issue of DC's post-Zero Hour Legion of Super-Heroes, Magno, a character from a world where - as his name implies - almost everyone has powers over magnetism, observes that on his world mining is still done by sapients because nothing else can replicate the flexibility of their powers. On most all other worlds, such work is done by robots, although in the same continuity the planet of Orando is governed by a ruling class of giant snake people and labor is done by a second-class citizenry of raccoon people.
- In the Marvel Universe, one of the most valuable materials in the world must be mined by hand. Antarctic Vibranium breaks down the structure of metals (indeed, this is the main reason it is so valuable), so mining machines are simply too expensive to be practical.
- In the Dark Horse Comics adaptation of The Terminator, Skynet initially puts surviving humans into labor camps. As with The Matrix, one might assume that this is done mainly for vengeful rather than practical reasons.
- Both inverted and played straight in Judge Dredd. One the one hand, in the cities of the world, robots are so effective for so many things that unemployment rarely dips below 85%, causing mass boredom, which in turn leads to massive crime levels. Conversely, penal servitude in the Cursed Earth is a fairly common penalty, and is commonly meted out to those who smash robots in order to be able to work. That type of criminal tends to jump at the opportunity to get back to work.
- Star Wars: Wookiees and Mon Calamari are enslaved by the Empire, but given the Empire's formidable military-industrial infrastructure, the omnipresence of droids, and the latter species' unusual physiology, alien slavery in the Empire makes little practical sense. (Droid slavery, on the other hand...) It seems slavery in the Star Wars verse is largely a policy intended to humiliate and degrade acceptable targets, when it isn't a cover for genocide (any parallels with Nazi Germany are probably intentional). Organic slaves are also seen a status symbol, but that's more for, er, personal needs. In particular, the, er, export of female Twi'leks from Ryloth is one of their most important industries. The resulting decline in the planetary population is the entire point; the Twi'leks essentially sold themselves into slavery to get *off* Ryloth. Evolution does not proceed to a perfect adaptation, only a reproductively sufficient one. The Twi'leks found the sufficiency of their adaptation extremely marginal.
- Wookiees and Mon Calamari are described as being favoured for slave labour due to their strength, dexterity, creativity, and intuitive understanding of mechanics and electronics, making them ideal for engineering work. In addition, the prequels reveal that the Wookiees helped Yoda escape Kashyyyk; Palpatine might have decided to enslave them as punishment. It is also implied that the main customers of the slave trade are from worlds which don't have access to advanced technologies (Ryloth is a Tidally Locked Planet only inhabitable on a narrow strip between its permanent "day" and "night" sides, limiting their economy).
- In the EU novel, The Rise of Darth Vader, this is confirmed: Kashyyyk was punished for harboring fugitive Jedi and fighting Imperial troops sent to retrieve them. However, while the Wookies and Mon Calamari are used for their technical skill by The Empire, it backfires on them: Admiral Ackbar started as Tarkin's slave before escaping to the Rebels, taking valuable intelligence with him, nearly killing Tarkin, while the Wookies sabotaged everything on the Death Star they could.
- Czerka wasn't a subsidiary of the Sith, but they sure were cozy during the Jedi Civil War. Wookiee labor was used in places where it would be too expensive to use and keep repairing droids, and was a revenue stream for Czerka while they found out what else the planet could get used for.
- In the EU, the spice mines of Kessel were a penal colony worked by prison labor as punishment (especially of spice smugglers); when Luke puts an end to this, the Republic, at his suggestion, keeps the mines in operation, still worked by living beings. This time, however, the miners will be paid, and hired from species who have evolved in the same sort of environment. The dark and cold and tight confines of the tunnels make droid mining impractical.
- The Terminator series has humans being rounded up and used for slave labor by Skynet in the post-Judgment Day future. Most noted among their uses for slaves was forcing captured humans to throw corpses into furnaces. The reasons for using humans rather than automated systems are never made clear, even in the fourth film which takes place entirely after Judgment Day and featured the final fight in an automated terminator line.
- The Sarah Connor Chronicles implies that Skynet's resources are actually extremely limited - which makes sense since a nuclear war would not only wipe out key infrastructure for Skynet such as mines and smelters, but also eliminate much of the upper-tier technology that was Skynet. In such a case, human slave labor might actually make sense.
- The American Astronaut has an entire planet chock-full of miners whose most advanced technology in the planet seems to be helmets with flashlights on it.
- Metropolis is big on this. The workers we see are mostly in charge of monitoring and operating the huge machines that run the city, in a work environment that seems to be needlessly oppressive and dangerous. Most of what they do would probably be computerized nowadays, but said computers weren't around in 1926. Also, we only see the laborer's running the "control center" of the city, we don't see the thousands probably digging coal into boilers or stacking rocks, or what-not.
- Moon neatly averts this trope, featuring a vast lunar mining facility staffed by exactly ONE human, who mostly serves as a troubleshooter for the automated systems. He is, however, essentially a slave himself, and cloned to boot.
- In Battlefield Earth, the Psychlos are an alien race advanced enough to take down Earth's entire armed forces in a matter of minutes, but Terl is using humans to mine in the radioactive areas (where Psychlos wouldn't be able to breathe) instead of traceable machinery; because he's running a thoroughly against the regs side project. This being a bad idea is kind of the whole point of the film.
- Inverted in the 1984 film Runaway, in which the mass harvesting of vegetables — a job which is still mostly done by peasants in Real Life — is performed by robots, even though robots throughout the film are prone to destructive malfunctions.
- In Future War, humanity is enslaved to do physical work because "the masters have no hands" (how they managed to enslave humanity and dinosaurs in the first place is another matter), even though there are cyborgs available that would presumably be more suitable.
- In The Unearthly (a John Carradine horror movie that was once featured on MST 3 K), a mad scientist has a bunch of caveman-like mutant rejects in one basement room, most of whom are apparently pushing a large electric turbine around in a circle, like the giant mill that Conan the Barbarian had to push when he was a slave. Not a terribly efficient source of power, all things considered, but at least he's putting his rejects to work!
- Surprisingly averted in the original Total Recall (1990), as this film's actual heavy mining is only seen being performed by machines. Although this begs the question of just what those downtrodden masses whom the Big Bad villain exploits, and the rebels are fighting to liberate, are doing at a Martian mining outpost, in the first place...
- Transformers: Dark Of The Moon has this as the overall villains plot, capture the entire human race to use them to rebuild Cybertron.
- Lampshaded and justified in Daleks' Invasion Earth: 2150 A.D., in which the Daleks use human miners because the magnetic forces in the mine's shaft would hinder their own functions or those of their machinery.
- The Honor Harrington books are set in the year 4000 with Faster-Than-Light Travel and nanoviruses that can mind control people, yet Manpower, Incorporated is still a very profitable concern. It makes genetic slaves to order for whatever you want: sex, other entertainment, heavy labour, etc. It is only in the latest book, Torch of Freedom that people start noticing that Manpower makes no economic sense, and should have gone broke ages ago. Manpower is really a cover for the Mesan Alignment, which is bent on galactic domination through genetic engineering.
- One would think that the sex slaves alone would pay for the whole business.
- Manpower's business model is generally considered to be sound, just horribly cruel. Their 'pleasure models' are highly profitable and very popular with a certain subset of the upper-classes, not to mention coming with a built-in black-mail hook. Even their industrial lines make more sense than a lot of example of this trope; they're mostly highly-skilled technicians, not manual labourersnote (although there are some examples of manual labour as well, pointed out in-universe as inefficient). The part that starts to tip people off that there's more to them than meets the eye is how they insist on getting mixed up in things that aren't their business, when they should logically just write it off as an unavoidable expense.
- In Jerry Pournelle's Falkenberg's Legion series and its spinoffs, the colonized planets generally have little or no industry or infrastructure, and the CoDominium keeps shipping convicts and dissidents to them whether they like it or not. In particular, Haven, Tanith, Frystaat, Thurstone, Arrarat, Hadley, and Sparta all have a permanent underclass, with degrees of unfreedom ranging from "can't vote" to "outright property".
- Dune. Justified in that after the Butlerian Jihad, complex autonomous machines are forbidden for millennia. Even regular old calculators are replaced by (highly-paid) people called Mentats.
- Most of these are Buddislamic slaves "harvested" from primitive worlds. The justification: their ancestors refused to fight machines, so the descendants have to pay the price. Even more, they should be happy to do their part.
- Even the Ixians, whose entire planet is a giant underground machine factory (they are the ones who build the enormous Guild heighliners) use throngs of suboids, a specially-bred race of humans mostly incapable of independent thought. This is considering that factory machines like the ones we have don't need to have complex computer "brains", which is what they're really afraid of.
- Interestingly enough, even Omnius in the prequels chooses to use human slaves instead of the more efficient machines, although that seems more of a status thing (i.e. putting humans below it).
- Brave New World uses the lower (read: intentionally retarded) castes to perform manual labor, and has even perfected technology to create multiple clones of the same human being (with the stated reason to ensure consistency). They have stopped developing technologies and need a large consumer base - both of which are to ensure societal stability. Of course, one reason they stopped developing technology was so that the lower castes would not be put out of work. (One of the characters claims that they'd tried a settling a fully-automated island with only the ruling class Alphas, as an experiment, and it collapsed into civil war within a year because they all wanted to be on top, while an experiment with giving people more leisure time in Ireland caused an overuse of the government-issued pleasure drug soma and general unrest since they had idle hands.)
- In William King's Warhammer 40,000 Space Wolf novel Ragnar's Claw, a spaceship operated by the Inquisition is tended by enslaved criminals, who are kept chained to the machines they work, and starved or tortured for disobedience. The next book's narrator contrasts it directly with a ship operated by the Space Marine chapter itself, which has an all-volunteer crew drawn from Space Wolf-protected planets.
- In H. Beam Piper's story "A Slave Is A Slave", Aditya became a feudal world of a few masters ruling a population of slaves after the fall of the interstellar Federation. One of the characters notes that slavery is economically inefficient compared to automation, but was apparently instituted to help the ruling class keep control.
- Slavery is a major theme in Charles StrossAccelerando. The very first chapter is about the precedent that prevents artificial intelligences and uploads from being treated as property. One protagonist is a male submissive; his daughter sells herself into slavery to herself to get away from her mother, taking advantage of a loophole in Islamic law. the alien and later human-made sentient corporations use minds as a currency. But manual labour itself is more or less entirely obsolete, what with The Singularity.
- The Uplift Universe, based on the works of David Brin, works on the principle that each sentient race will create new sentient races, from modifying lower non-sapient lifeforms. These new 'client' races are then indentured to the 'patron' race for a period of 100,000 years. Patron races gain wealth and status based on this practice. When the indenture period has expired, the client races are then allowed full status to uplift new species for themselves, continuing the chain of uplift. This practice has gone on for 3 billion years.
- A scenario like this is used in-character in Martians in Maggody, when a reporter convinces two guilible locals that stealing copies of a UFO enthusiast's computer files is the only way to prevent scary aliens from enslaving humanity and forcing everyone to work in mines. Subverted in that the reporter is not only feeding them Dead Horse Tropes to trick them into helping him, he's not even a reporter. He's an IRS agent investigating the UFO enthusiast's unreported profits from book sales and lecture fees.
- Played straight in the mines of Kessel. Use of anything other than manual labor risks exposing the glitterstim spice to light or heat and reducing its value and potency. Lampshaded heavily in the book that introduces this explanation. There are species in the galaxy that consider the cold, dark mines an ideal environment and after leading a revolt, Luke decides to keep the mines operating, using paid labor from such races. Glitterstim does have medical uses and it was always legal-just so high priced that a thriving black market for it existed.
- Subverted in the Rogue Squadron series. The various prisoners of Lusankya are, to their knowledge, used as slave labor in mines. In fact, the mines are a deception meant to keep the prisoners from finding the actual escape routes and the manual labor is just a form of distraction and punishment. The labor simply consists of breaking rocks up into sand anyway (which was common for useless make-work performed in real penal colonies).
- In Nova by Samuel R. Delany, everyone in the future has cyborg implants that allow them to interface with machinery, letting people control any machine, from vacuum cleaners to spaceships, and pseudo-physically perform labor through them—not quite manual labor, but not using robots. While it would be possible to automate everything, it was found that people have a psychological need to connect their actions to work rather than letting robots do everything for them.
- Subverted with humans in The History of the Galaxy books, who strive to computerize anything and everything. In fact, at least one Mega Corp. creates new colonies by sending a completely-automated factory. Human workers are only added in later stages to oversee the operation and expansion. Played straight with the Insects, who had highly-advanced technology 3 million years ago but have never had the need to develop complex machines due to their enormous work force, which is created by artificially de-evolving intelligent members of their race into mindless drones. This process is completely reversible, making their race extremely versatile.
- In The Caves of Steel, a major source of contention between Earthlings and the Spacers (former planet colonists from Earth, now rebelled) is the refusal of Earth to stop using manual labor. Robots could do all the work better, faster and safer for only a fraction of the cost, and are one of the key reasons for the utopian societies of the Spacers, but their introduction to Earth society is being resisted (sometimes violently) because they will displace so much of the human workforce.
- Appears as an Unbuilt Trope in The Sleeper Awakes. Being written before Fordism and mass-production, the future society contains a large slave class which is initally presented this way. It's only revealed late on that in fact manual labour is almost obsolete and the future slaves simply operate the machines all day.
- The Myst tie-in novel The Book of D'ni introduces the Tehranee, a race of people so advanced, especially in engineering and chemistry, that they are universally indolent, wiling away their days in the pursuit of superior artistry and poesis, while the burden of building and maintaining their vast artworks is placed on a huge caste of slaves. Worse, these people's linking technology allows them to travel instantly to any planet they can describe, giving them access to basically unlimited resources of every kind, which should make all forms of slavery utterly obsolete. Thus, the Tehranee preserve slavery apparently just because it's traditional and they can't be bothered to create a better system.
- In the Children of Steel novels animorphs are identured to the companies that create them for 50 years or until they manage to earn enough to pay the multi-million credit cost of their gestation and education. Or they die considering they tend to work in hazardous jobs. The Egypt-themed planet Pharoah goes so far as to practice outright slavery.
- In Vorkosigan Saga Jacksonians, being a Mafia-ruled planet often engage in slavery, though their most valuable slaves are less for mundane purposes and more for exotic things like replacing the brains of clones with those of rich men who wish for a rather vampiric immortality. On Barrayar slavery is illegal, but it's status as an unevenly developed civilization means that in many parts they will depend on manual labor, sometimes in nasty conditions.
- Conflict between the ruling class and large populations of essentially slave labor is central to the setting of The Hunger Games. At the same time, said rulers possess technology to among other things control weather (at least on a local scale) and piece together human corpses into living monstrous doglike creatures.
- Actually Justified in Space Vultue. It is apparently more efficient to use cheap, easily replaced slaves for certain forms of hard labor than to use expensive and hard-to-maintain robots.
Live Action TV
- Star Trek: Alien prisons frequently double as Gulag-style mines, like Rura Penthe in Star Trek VI: The Undiscovered Country. Romulus' sister planet, Remus, seems to be one giant mine and military-industrial complex. This is so overdone in Trek and other sci-fi to the extent that if a Starfleet officer, SG-1 team member, or other hero is arrested by an alien government, we can be assured that if the penalty is not death, then we can expect that they'll spend the rest of their days mining Stock Phrases in Expo Speak mode.
- The Federation does it to the EMH-Mark-Is (upon which Star Trek: Voyager's Doctor is based). This, when they have devices capable of disassembling matter to the subatomic level and ships that bend the laws of reality at command, not to mention a race of friendly living ore processors (the Horta). But no, they consign outdated humanoid holograms with glorified shovels and picks to mining. This implies that the Federation either does this on a wide scale, or that they specifically modified this mine to do such a thing. No amount of Fridge Logic can save this one.
- An exception appears in Star Trek: The Original Series, "The Corbomite Maneuver", where Balok is the commander and sole occupant of his Sufficiently Advanced spaceship, the Fesarius, which is dozens of times the size of the Enterprise.
- The Original Series also had "The Cloud Minders" [sic], about a planet that had actual floating cities for the ruling class, while the working class miners used hand tools and were exposed to brain-killing toxic compounds without even dust masks (this appeared to be Roddenberry's most blatant commentary on the class struggle).
- Star Trek: Voyager: In "The 37's" an alien race capable of travelling from one side of the galaxy to the other brings back humans from 1937 as slaves. Also done in Star Trek: Enterprise "North Star" though the distance was a lot less. Comparatively speaking.
- Cardassians did this to their Bajoran subjects, as Deep Space Nine's original function was as an orbital ore processing center. Its Mirror Universe counterpart Terok Nor still is with the exception that Terrans are being used as laborers instead of Bajorans.
- Firefly's relatively low tech-level makes this sort of thing more understandable; the use of indentured servants probably did cut costs for barons in The Outer Rim (tm), or was the only available option for them. And then passed the savings from using indentured labor right on to the customer!
- Slave labor is also used for terraforming crews on various worlds; according to one slave-trader, they have a "prodigious death rate" so selling slaves is a source of steady yet dubious income.
- Though we don't see them outright, it is implied that the Sex Slave trade is also around. When Mal discovers River in Simon's cryo-box, the first thing he thinks is happening is that Simon was smuggling her to be sold to "some Border-world baron."
- Farscape: Rygel XVI, deposed Dominar of the (interstellar-spanning) Hynerian Empire, makes frequent references to servants and slaves in his royal court. Humorously, when visiting Earth, he states that if Earth is to be remembered for anything, it will be for the quality of our manual labor.
- Stark's species, The Baniks, are referred to as an entire race of slaves, and it's implied that not all of the Baniks have Stark's mystical abilities. One must wonder why the Peacekeepers, Scarrans, and other militaristic, aggressive species don't just hire a few super-powered alien mercenaries (of which there are absolutely no shortage) to do the work of a hundred or a thousand near-human Baniks.
- Farscape also raises the interesting question of whether Living Ships, particularly sentient ones, count as manual labour...
- That being said, Leviathans can do stuff that non-living ships can't (maintain themselves, starburst).
- Battlestar Galactica. Human beings in the ragtag fleet are forced to work in dangerous and unregulated mining and refining ships, but these are refugees from a civilization that turned its back on advanced cybernetics after fighting a war with the Cylons. Water extraction was apparently a dangerous occupation too, and the leaders of the fleet conscripted prisoners to do it in exchange for reduced sentences.
- It gets better. Said advanced cybernetic organisms, the Cylons, also have a "tiered" society where mindless Centurions and non-sentient Raiders do all the land and space fighting respectively, while the humanoid "skinjobs" control the Baseship's female command oracle. This eventually comes back to bite them when the Raiders gain a degree of sentience, half the skinjobs decide the Centurions deserve full sentience, and an Enemy Civil War breaks out.
- The old Doctor Who enemies known as the Dominators were looking for slaves (and evaluated the Dulcians for that purpose) because, though they did have the robotic Quarks for labour, the Quarks were also better at fighting, so they were replacing them in the labour areas and using them in an invasion.
- The Ood from the new series are described as "your basic slave race". In this case, they want to be slaves, as it gives them a purpose in life. At least, after the standard lobotomy as part of their "manufacture" as slaves, that's what they want.
- A minor variant of this trope, too; Ood are often shown in personal servant, or at least human support, roles. The ad shown in 'Planet of the Ood' itself is of one offering tea.
- Played with in the novel Prisoner Of The Daleks, a Space Marine points out that Daleks do have tunnelling equipment that could do the job of clearing rubble in minutes. But Daleks enjoy subjugating other races.
- A lampshade is hung on this in the Outer Limits episode "Feasibility Study", where aliens bring humans to their planet as part of an attempt to find slave workers. When one of them explains this plan to one of the humans, the human exasperatingly asks what use they could possibly have for slaves when they have the technology to move a giant chunk of a distant planet thousands of light years to their present location. The alien sheepishly responds that they consider using this technology for menial labor to be demeaning.
- Some prides of Nietzscheans in Andromeda use slaves, or capture slaves for other people. But, since AI in Andromeda is advanced, and many episodes of the first season showed simple humanoid robots doing work on Andromeda, Nietzschean slavery is mostly a Kick the Dog convention to show how evil some Nietzschean prides are, particularly the Drago-Kazov.
- Somewhat justified by the postapocalyptic setting; though some groups have access to the remnants of Commonwealth technology, many do not and have to make do with cruder methods.
- There's also that the Nietzscheans like to conquer other planets, and, well, you have to do something with the population you've just taken over, right? Might as well put them to work, its cheaper than having to dig all their graves yourself.
- A non-future version comes up in the Tales of the Gold Monkey episode Black Pearl. Those Wacky Nazis are assembling an atomic weapon and preparing it for testing using enslaved islanders. When one Nazi complains about the inefficiency of this, as well as the use of torches for light when electric generators are readily available, the other says that it appeals to his sense of drama.
- The Goa'uld of Stargate SG-1 love sending pickaxe-equipped slaves to their Naquadah mines, but this is partially justified: The Goa'uld may have access to advanced technology, but they also really, really like ordering people around and being worshipped. Also, they are largely unconcerned with doing things efficiently, instead preferring to do things impressively, or For the Evulz. This is explicitly said to provide the Good Guys with one of their main advantages against the Goa'uld. It should be noted that the Goa'uld quite logically did not want to provide advanced technology to their slaves, so while they themselves rode around in fancy starships, their servants largely lived on dung age planets. That said, there were earlier instances of Goa'uld using some automation. One pre-Anubis episode featured a Goa'uld robotic probe that was seen exploring a planet on its own, and Teal'c believed this was a brand-new development — the task might have previously been assigned to bands of Jaffa warriors. However, remember the Goa'uld were not interested in power for some pragmatic purpose, but in power itself. They saw themselves as gods, after all, and competed through showmanship and intimidation as much as through things like production and military efficiency. An inefficient army of terrified slaves might impress a Goa'uld's rivals far more than an efficient machine doing the same job in half the time. The show frequently acknowledged this as the Goa'uld's key weakness. The Ori continued the trend. Even with all the knowledge of ascended beings, their ships are still built by their primitive human worshippers.
- The Tectonese from Alien Nation had been slaves before their accidental arrival on Earth. Subverted in that, while their great physical strength is suited for manual labor, they're also extremely fast learners, whose jobs while enslaved usually entailed a lot of technical know-how.
- A first season episode of Babylon 5 revolves around a major labor dispute with the station's dockworkers' union, which seems to use this trope. The situation is defused when Sinclair diverts funds from his military appropriation to fulfill the strikers' demands. The Senate's professional strikebreaker complains that he's being a Rules Lawyer with the Senate's order to end the strike by any means necessary, and Sinclair tells him to go jump.
- Warhammer 40,000: Everyone except the Necrons and the Tau use manual labour. The Imperium has a phobia of effective robotics because A.I. destroyed their civilization once. The rebellion of the 'Men of Iron,' Man's robotic soldiers, was a major factor in the Age of Strife which ended their Glory Days, destroyed a vast majority of their technology, and preceded the founding of the Imperium. The Eldar need to keep themselves busy all the time to keep their psychic minds from paying attention to Slaanesh (and they don't do dangerous industrial work anyway; everything is made by wraithbone). The Orks are just... limited. Chaos forces and Dark Eldar use slaves because it's more fun that way. Schizo Tech is common in 40K; it's the only place where your starship is powered by plasma reactors but you need thousands of press-ganged shanghaied deckhands to load its guns. With ropes. While being whipped.
- Not because the Magos on board does not know how to build a decent automatic and mechanized loading system (He knows how, even if he doesn't know why it works), it's because beating some people over the head to do it manually is far cheaper and easier in an overpopulated universe where technology is rare and often archaeological.
- Also most of the manufacturing is done by 'servitors', which are lobotomised cyborgs used for manual labour (although they are often equipped with heavy weaponry in combat situations), made up of heretics, criminals, etc. (though most are actually just human blanks grown in vats; servitors use human brains as Wetware CPU, due to AI ban), then completely mind wiped, drugged and many of the organs/limbs replaced with more 'efficient' robotic equivalents. In 40k, cybernetics is ubiquitous and easier to control (as in, one of the least grimdarked-to-hell elements in the setting) than the aforementioned Iron Men. The Forge Worlds (run entirely by the Adeptus Mechanicus) are responsible for producing the monumental amounts of equipment needed daily by the Imperium of Man, have a relatively small human population, for example Mars (The first human colony and the headquarters of the Adeptus Mechanicus) has a population of 20 billion, while the Hive World Ichar IV (before it was consumed by the Tyranids) had 500 billion and produced far less (particularly when the Genestealers showed up).
- It doesn't help that said Adeptus Mechanicus acts like an autonomous Mega Corp. that monopolizes any advanced technology, from Humongous Mecha to simple automated systems, in the Imperium. Any independent scientist or research organization that gets too popular will be forcibly bought, assimilated or killed by the Adeptus Mechanicus, who think that advanced archaeotech obtained from Precursors are better than independent innovation. They entirely have the capability to build an army of automated servitors to do the fighting for the Imperium, only that they think they're the only ones in the entire universe who have any idea about something arcane and forgotten called "Science", and hence hate to share it openly with other factions of the Imperium, who in turn don't fully trust the Mechanicus and consider them as borderline heretics who get away with it because the Mechanicus answers only to the Emperor himself, and are responsible for personally maintaining the Emperor's life-support system. This forces said other factions to instead rely on manual Mooks which are far cheaper than hiring servitors and a Techpriest who will maintain the automated systems.
- You don't need intelligent machines to load shells into a cannon. You could build a perfectly serviceable motor control circuit for that using nothing more advanced than copper wiring and magnets. Probably get a better rate of fire out of it, too (removes the chance of the whipper making the whip-ee drop the shell instead of load it). Tau railgun work that way too.
- It should be noted that on the scale of Warhammer 40,000, a 'shell' could vary in size between a bus and a small skyscraper.
- Ultimately, all of this is reflective a curious (and abhorrent) form of dealing with scarcity. Due to the constant war, constant strain on resources, overpopulation, and loss of technology, the Imperium has quickly found that the one resource it does have for free are human bodies that keep breeding more and more like a bunch of tyranids. Thus, while it may be more efficient in the instant case (i.e. an individual starship) to build an autoloader for your skyscraper shells, on the galactic scale, the materials needed to build such a loader are far, far more desperately needed to maintain the already-existing archaeotech, and/or build lasguns and M2 Browning heavy machine guns (yes, the 100 year old design is still in use, more or less unchanged, 38,000 years in the future).
- One of the gangs in Necromunda is made up of escaped slaves. While they act as manual labor the trope is played with as they are implanted with machinery like drills to do their work.
- There are practical benefits as well. An autoloader that is damaged in combat will probably not be brought back online soon enough to continue the fight, but if a work gang is killed off the rubble can be cleared and the workers replaced in a matter of minutes.
- GURPS Reign Of Steel has many of the AI Zoneminds keeping human slaves in a variety of ways and for a variety of purposes. This makes sense in many applications since robots are expensive to produce but human vermin are cheap and disposable. Notable cases include:
- Zone New Delhi and Zone Denver, which use human brain tissue or even whole brains as a substitute for expensive electronics to run lesser robots.
- Zone Moscow, which uses human agents to collect what remains of the libraries and artwork of human civilization.
- Zone Washington, where the human inhabitants believe themselves to be the sole remaining human-controlled nation and labour mightily to maintain the strength of their military robots to keep it that way - controlled, of course, by their 'tame' AI that in actuality runs the government.
- Some of the Zoneminds that have instead chosen to ruthlessly eradicate all humans immediately are actually at an economic disadvantage to their bretheren because of it, both due to the lack of cheap labor and the extra resources they've expended in the extermination efforts.
- Slave traffic is mentioned in Traveller. It is illegal in the Imperium, though the Sword Worlds have a judicial slavery as punishment for murder, treason, and other heinous crimes (which makes one amused at the Irony of the fate of a Space Pirate caught while trying to sell off his captives). It is not always made clear what the slaves are expected to do. However the Schizo Tech of Traveller at least sort of justifies it.
- This is almost to be expected in Rifts, given the Schizo Tech of the setting. Throughout much of North America, people are often enslaved or indentured, turned into cyborgs and used as miners. The Coalition doesn't use slave-borgs, but nonhumans are sometimes enslaved and employed in the mega-cities or the 'burbs. In magic-dominated places, meanwhile, slavery is widespread and slaves are used for any and every task, be it labor, warfare, Gladiator Games, sex or food (the latter is a big one, since a lot of alien evils do it to cement their Card-Carrying Villain status).
- In Fading Suns due to the Church's attitude towards technology there is a great deal of demand for manual labor. The Muster Guild specializes in providing workers though most of them are temps or outright slaves while members get cushy supervisor positions.
- In Eclipse Phase identured servitude was revived as a means for the Mega Corps and their Hypercorp successors to obtain cheap labor for their off-world colonies, it was accepted due to the expense of interplanetary travel, especially since the fastest means is to upload your ego into a new body at your destination. After The Fall there were suddenly billions of disembodied infugees willing to sign anything if it meant eventually having flesh again. The practice is condemned by most Autonomists, excepting the anarcho-capitalist Extropians who also practice debt slavery.
- Paranoia has ridiculously advanced robotics, but people who have worked their way up to the highest security clearances replace robot servants with human because robot servants are just so low-grade.
- Perhaps one of the earliest examples of this in video games is from Marathon, in which some of the slaves hack into the titular ship's AIs to hack and destroy them from the inside (as one of them is the only hope for the ship, and one plans to drive them to extinction), some are treated as worthless cannon fodder and are fired upon in deadly combat situations for fun, and others are seemingly tolerated combatants.
- Half-Life 2 has the "unwillingly made into cyborgs" version with Stalkers, people who have their limbs and most of their organs removed and replaced with mechanical equivalents, and appear to be brainwashed/programmed to near-nonsentience. The "transhuman" arm of the Combine Overwatch also appears to be a lesser version of this; the changes made are less radical and they retain more intelligence, however the process is voluntary. This was rather the point as far as Well-Intentioned Extremist Breen was concerned; it was either prove humanity useful in some way (anyway no matter how desperate) or face extinction.
- In Empire Earth, no matter what age the player advances to, workers will still chop trees with axes, mine minerals with picks and carry everything in a wheelbarrow. Even when soldiers are using giant mechas to move around.
- Somewhat averted in Rise of Nations, where your workers' tools advance with the age. Modern workers will use chainsaws and jackhammers.
- Lampshaded in Red Faction, where stereotypical futuristic Martian mine slave protagonist muses to himself about how robots should be able to do nearly all of the hard work themselves. It then turns out that robots do perform most of the real mining labor, and the human-heavy mining operation is really just a front for the Big Bad Evilutionary Biologist to get test subjects for his (honestly pretty pointless-looking) secret experiments away from the prying eyes of Earth's government. Note that RF originated as an entry in the Descent series, the premise of which centers around futuristic mines run entirely by robots (which have their own problems).
- In a Gaia Online event, each of the four towns was assigned two fantasy races to assist them in the upcoming "Rejected Olympics". The futuristic town of Aekea got Blizzard Style Orcs, in addition to the previously introduced Aliens. The new aliens were created by leftover Applied Phlebotinum that the real aliens left behind, while the orcs were Hand Waved away by saying they were a newly discovered species that have been hired as manual laborers. One character even wonders if the orcs are actually being payed for their work. ...Of course, there's just one problem. AEKEA IS A CITY FULL OF ROBOTS. It's the only city that's even allowed to have robots, as they were banned everywhere else after some war that no one talks about. But the fact that you are enslaving orcs to effectively do something that could be accomplished by a tow truck or a pulley is a bit confusing...
- In EVE Online the Amarr Empire makes a wide use of slaves. Although they could easily replace most of their slaves with advanced technology, like the other nations have done, the Amarr believe that, by enslaving "lesser" peoples like the Minmatar, they are saving these people's souls. It's no surprise that the Amarr are quite far behind technologically when compared to the Gallente and especially the Caldari.
- The second Crusader game, No Regret, makes a few things clear. First, the most valuable mineral in the solar system is found almost exlusively on the moon—almost half of known reserves are there. Second, the WEC ships mostly political prisoners there, to get them out of the way and do mining with minimal safety while surrounded by heavily-armed guards. Third, the game's own lore states that while semi-sentient guard robots and maintenance bots are present, they are apparently quite expensive, compared to unprotected laborers operating nonsentient machinery with guns pointed at their heads. Played straight, justifed, and subvereted all at once.
- Subverted in Tales of Symphonia when you eventually learn the slaves in the Magitek human ranches aren't there for any real work. The bad guys just need them to waste away while the implanted exspheres feed off of their anguish.
- The batarians in Mass Effect still practice slavery, despite a being starfaring civilisation for centuries. They argue that slavery is a "cultural right" of their people; the Council doesn't buy it.
- Slavery is also practiced on the asari planet Illium. Only it's called "indentured servitude," thank you very much. It's considered perfectly legal and is tightly regulated with restrictions on treatment and terms of service, legal requirements for documented consensus on the part of the servant, and strict limitations on how long the servant can remain indentured. It should also be noted that indentured servants aren't necessarily physical workers; they can be practically anything and are contracted to do a normal job for a company or individual. Well, just without pay. Or the ability to leave. Or... You get the point. One indentured servant you meet on Illium is a software engineer who had a gambling debt problem.
- A variation in World of Warcraft: the Pit of Saron instance takes place in/around a large open-pit mine being worked on by undead miners and slaves captured from the Alliance and Horde armies. Fair enough. But when the players lead the Inevitable Slave Revolt against the overseer, you might wonder - why would the Scourge bother with living slaves when they could just kill them, raise them from the dead, and have undead slaves? Undead don't need to eat, after all, and mindless skeletons won't be plotting revenge any time soon.
- Tell that to Sylvanas and the Knights of the Ebon Blade...
- I think the best answer to the question is the simple answer: Arthas is a dick.
- Arthas does have to mentally control his undead forces, as the ending to the Icecrown Citadel raid demonstrates. The more autonomous his servants are, the more free will they must be given. Considering the aforementioned Ebon Blade and Forsaken, it may simply be better to have living miners that must fear for their lives over undead that have been given enough will that they might break away and join the Forsaken at some point.
- Command & Conquer Red Alert 2: Yuri's Revenge has Yuri's faction practise slave labour, even though Yuri has genetic manipulation, mind control technology and a laser-armed UFO unit that efficiently extracts ore from enemy refineries. However, consider that Yuri is a madman, and the "Slave Miner" vehicle's driver lampshades the act by saying "Slaves are cheap!". It also gives the other two nations even more reasons to fight Yuri, and freeing the slaves is actually possible.
- In Elite you could trade in slaves, though it would mean your legal status would take a hit. You could even accidentally pick up slaves if you scooped up an escape pod from an enemy ship (and there was no way to free them, or hand them over to the cops). Open Source Remake Oolite fixed this by offering a small reward paid out from the survivor's insurance policy instead, and occasionally a bounty from the local police if they turn out to be a wanted felon, but you can still do it anyway if you feel like being a dick.
- In Galactic Civilizations 2 the Drengin and Korath have slave pits instead of factories. They claim that slavery is an inherent part of their culture, and their society would collapse without it. Then again, they also see brutal torture of said slaves as entertainment. Their science buildings also work by sucking the brainpower (and even thoughts and dreams) out of slaves' minds.
- This is actually the reason why the Drengin and the Korath enter into an Enemy Civil War. Thaks to the Dread Lords' influence, the Korath decide to wipe out any non-Drengin from the galaxy (they actually succeed in wiping out two races). However, since the Drengin economy hinges on slaves, they can't have the Korath be doing that.
- The backstory to the first game even shows the lengths the Drengin will go to in order to get slaves. Millennia before the Arceans made First Contact with humans, the Drengin were sending out sublight probes to other stars to map them out. They discovered the Torians and decide to conquer them. Since, until the humans invented the hyperdrive, all races had to use static hypergates, they spent 75,000 years dragging a hypergate from Drengi to Toria and an additional 5 years for the conquest fleet to arrive after activating the gate. Now that's commitment! Of course, it also made it easy for the Torians to overthrow them. They simply shut down the gate after fighting off the planetary garrison, preventing any reinforcements from being sent. It's heavily implied that this would have been the fate of the humans had they chosen to activate their gate when the Arceans sent them the blueprints.
- In the Terinu universe, the hyper-advanced Varn Dominion used slaves a great deal, but it was regarded as culturally necessary since their gods had declared they were the Master Race and deserved to rule over the lesser races and have their every whim catered to. Five hundred years later, the good guys' successor government permits the use indentured service as punishment for criminals (with one Jerk Ass Protagonist declaring it was "Cheaper than letting them sit in a cell and eat up public funds"!), and just good old-fashioned corporate evil as isolated industrial facilities bind their workers through indenture and selling their souls to the company store.
- An episode of Futurama has the crew enslaved on an Egyptian analogue planet, where thousands of people are worked to death for laughs to build huge monuments and tombs. Bender gets himself named Pharaoh and takes it up to eleven.
- In another episode, Hermes and LaBarbara Conrad unwittingly vacation at a forced-labor "spa".
- In Teenage Mutant Ninja Turtles, Krang is the proud owner of the Technodrome, with all the Mecha-Mooks he can use. He and Shredder still force Bebop and Rocksteady to do all the cleaning work around the Technodrome, even though they are lazy and incompetent enough that it would seem more efficient to have the work done by robots.
- On the other hand, it kept them out of trouble -mostly- when they weren't needed for anything else. Bored, restless Dumb Muscle is never a good thing.
- The SpongeBob SquarePants Movie
- Many people just prefer the handmade version, and handmade crafts are considered staples of high luxury, even if they have to make it themselves. There are TV shows, books and even art projects all about doing things the "old fashioned way" or "as they did back in ___". Oddly enough, people are using 3-D printers to make hand tools, overlapping with Schizo Tech.
- Cosplay is a good example, most cosplayers will make their own costumes. Ditto Goth, Gothic Lolita and other "do it yourself" fashions promoting hard work and original looks. They will mock those whose hardest work is swiping the credit card.
- In general, making clothing will be hard to fully automate until our robots can manipulate a needle human-style and visually perceive fabric in three-dimensional space - there are basic tasks even a human-operated sewing machine isn't really good enough for. In some ways costume making emulates the production of "high fashion" (the designs which eventually get modified for machine sewing and trickle down to department store exclusive collections and the like) and given the manpower and budgets behind those outfits, learning to sew actually is the economical option, even if your goals are more realistic.
- Cooking is another. Cooking is a complex art and science that actually requires a lot of skill, and making an automat for every single recipe will be costly. The Fifties promised us a Jetson's kitchen complete with Food Pills. Many of the "labour saving devices" never really caught on, except the blender and food processor. We know more about diet now, many people shun processed foods for their inherent tastelessness that's compensated through high sugar and fat content. Modern day gourmet food is preferred to be prepared through ordinary kitchen utensils and hard work (and organic food grown locally from small farms).
- Taking advantage of their food being very heavily standardized, McDonald's once experimented with a robotic kitchen, going so far as to build a Hong Kong outlet that used one. They scrapped the idea, but not the outlet, when the construction and maintenance turned out to be far more costly than employees. Their one fully automated outlet is still there, as a minor tourist attraction, but building more isn't worthwhile with today's technology. Likewise, "vending machine" restaurants are seldom seen today even as curiosities, because of the complexity of food preparation. Thus it's cheaper to train maneuverable high school kids than to maintain the equipment. Same thing goes for having a small, well-trained staff that makes complex food. These people will usually be harder to replace, or wield more clout during employer-employee conflicts. It's just more convenient with fairly untrained, unorganized kids, most of whom do not expect to work there more than a few years, if that.
- An interesting historical case: Ancient Greece. Towards the later parts of its history, this society seemed to be teetering on the brink of an industrial revolution, but never quite made the plunge, instead sticking with slavery and other traditional, labour-intensive methods of production. Ancient Greece had a great deal of scientific thinkers, the capacity to build complex mechanical devices, and even developed a simple steam engine. The steam engine especially, if developed further and perfected, could have been used to simplify a lot of labour-intensive jobs, as it was when the Industrial Revolution finally did roll around. But the Ancient Greeks saw it as nothing more than a curious toy.
- Those that did think the steam engine was great tended to not be taken seriously. One guy was pretty sure that Hero's Engine could be used to predict the weather. Given that the boiling point of water varies depending on air pressure, and that quite a bit of the weather is dependent on moving high/low pressure fronts, he was probably actually on to something. Ancient Greece also had several factors working against it that are considered a requirement for industrialization. First, their technology base was actually very low, to the point that they had little access to high grade iron for a good steel industry, and bronze, while a good substitute in many things, is also more expensive than iron and steel. Second, they had no real centralized polity to ram the reforms down their throats. Third, they would not have been able to afford it even if they did have a fully centralized authority. They actually saw the potential, but wrote it off as a case of Awesome, but Impractical. Even the Romans, who could have possibly done it to a limited degree, would not have been able to fully pull it off for the first and third reasons respectively. The nations of Europe in the late 18th century which kicked the industrial revolution off actually had more concentrated wealth individually than the entire Roman Empire at its' height.
- Consider also the medieval Chinese, who invented so many amazing feats of chemistry, engineering and metallurgy yet somehow were eclipsed by the western European nations and remained a bit of an industrial backwater for hundreds of years. Though much of this was cultural, as Confucianism taught rigorous adherence to the status quo. The Chinese were never able to separate philosophy from religion and they were never able to invent the scientific method. They did have all the ingredients for the scientific and technological revolution, but they never made the final breakthrough. Once that was introduced from outside, however, China has rapidly risen to the spearhead of technology.
- Autoloaders for tanks and artillery free up some room, and save weight (for artillery anyway) but are notoriously unreliable. With one you only need 3 people (driver, commander, gunner), not 4 (the loader) and any weight saved can be used for extra armour. During the Cold War the Russians had auto-loaders in their tanks. The US Army never used them, even on the M-1. Why? The auto loader added weight and complexity and a 19 year old with a strong right arm was faster than any auto loader. As for the unreliability, the Russian auto-loaders were famous for their habit of catching the gunner's sleeve and trying to load his arm, and sometimes succeeding.note They do see use in NATO artillery, and large-calibre autoloaders can easily outload humans (6/2 rounds/min rapid/sustained for the manual loaded AS-90, but 10-13 rounds either way for the auto-loaded PzH 2000). Not to mention that the 19 year old is a lot more versatile than any autoloader, he can help you change a tread, watch your back while you make repairs, or fill in for a comrade if they get incapacitated. This is explained by differences in doctrine. Soviet tanks were small because a) smaller tank is harder to hit, and b) smaller tank is easier to armor — it can have a thicker armor for a given mass, or a smaller mass for a given armor thickness. The combination of a small tank and thick armor made for a very cramped interior (Soviet Army had a maximum height requirement of about 170 cm for the tankmen recruits), and there was simply no place for the fourth crewmember, hence the autoloader. French tanks use them mainly for the same reason, as their tank doctrine also prefers the smaller profiles and tighter internal layouts. Another problem with Soviet-style autoloaders is their Ammo Placement where the M1 had it's ammo in one area and blowout systems, soviet tanks usually just stuck them in a ring around the turret. Yes, the most likely place for an enemy shell to hit is where they put the ammo. One doesn't have to be a rocket scientist to figure out what happens when it does get hit.
- Large Chinese electronics manufacturer Foxconn, which produces a lot of various gadgets for big name brands, including all Apple products, traditionally employs manual labour on its assembly plants, specifically because putting a lot of former Chinese peasants, orphans and abandoned little girls into a sweatshop and running them till they drop is much, much cheaper than investing into a First World Japanese-style automated assembly line. This also means that Chinese "Gross Domestic Product = economic development" is actually a misunderstanding: GDP is only the average value of the products that go out of the country (e.g. Apple products and cheap toys), while real economic development is more accurately measured through Per Capita Income (as in, the actual profits for the average prole), and guess what, said Chinese peasants and little girls have almost the same minimum wage PCI as third world countries, while the GDP profits goes to executives at Foxconn and then Apple.
As time passed on, though, overall Chinese economic growth meant that fewer and fewer people are willing to tolerate harsh working conditions and meager pay, so the labour unrest became a problem for the company. Add to that the calls for product boycotting from the labour action groups and displeasure from the brands itselves, who are conscious about their image, — and cue the news that Foxconn is investing astronomical sums into the automated assembly. Robots may be more expensive in the long run, but they don't make a fuss and don't beat the managers half to death.
- Sailing. No matter the size of the boat, anything from hauling the sails to changing the tack is done manually. That because yachts are usually cramped boats with little space for extra machinery, and because technology has a tendency to fail when least expected. Besides that, crewmembers are easily moveable ballast where extra weight is needed. Back when steam had only started to make inroads, huge crews that sailing ships had were their second main disadvantage after their reliance on the weather. Steamboat might've needed a place for coal and thus carry less cargo, but it could be manned by twenty sailors instead of more than hundred like a sailboat of same size. So the mechanical winches were installed, sail plans simplified, emergency engines mounted, and last cargo-carrying sail ships actually had remarkably small crews, not much larger than steamships, with sailors almost never going aloft. But then is was discovered that sailing makes an excellent practice even for steamship sailors. And so the tall ships were born — a mobile classes of various marine schools, which are intentionally built in the old-fashioned way to teach the cadets what the sea really is. There are several unconventional and very high performance designs that use sail-by-wire or computer controlled sail trimming... the Walker Wingsail design is nearly 20 years old and the Vestas Sailrocket is a later design capable of 65 knots under sail power. There's still no substitute for something that can be repaired and driven by hand though, given that you don't want your motors to seize up or your electronics when you're several days or weeks sail away from land...
Break time's over! Back to the spice mines, worm!
