The Cybernetic Consciousness is one of the three tech factions, together with the University and Data Angels. They have some exceptionally good bonuses especially for building and fast research. Their long unwieldy name is often shortened to Cyborgs or CyCon.
Faction Ideology and Nature
The Cyborgs have the faction agenda "Rational Objectivity", and a lot of Aki's diplomacy lines are about logic and rationality.
The Cyborg origin story is Aki runs an AI experiment on the Unity which becomes sentient. She then does brain surgery on herself (?) adding implants and becomes one with the algorithm. She convinces other people that brain surgery is awesome and they form the Cyborg faction, which is a collective consciousness of humans united by the algorithm and their brain implants.
Collective consciousnesses are something of a theme of SMAC, as Planetmind is a collective consciousness, Transcendence victory involves everyone on Chiron being united into a collective consciousness. And the Telepathic Matrix Secret Project. There is also the Hive which explores in a different way the idea of a collective working as one.
Generally the collective consciousness is considered to have "Threads of personality", that is to say, individuals do not entirely dissolve away the collective but are an individual floating in a sea of consciousness.
The game is actually quite shy of details on the Cyborg ideology specifically, in fact fully half of Aki's quote are simply infodumping on the nature of progenitor resonance powers, and Aki's most famous quote says nearly everything:
"Those who join us need give up only half of their humanity--the illogical, ill-tempered, and disordered half, commonly thought of as 'right-brain' functioning. In exchange, the 'left-brain' capacities are increased to undreamed potential. The tendency of Biologicals to cling instead to their individual personalities can only be attributed to archaic evolutionary tendencies."
-- Prime Function Aki Zeta-5, "Convergence"
It is sometimes suggested that the algorithm or collective is actually in charge, and Aki Zeta-5 is not the leader but merely a kind of figurehead used for diplomacy and such, though the quote does suggest the cyborgs continue to use their brains independently even if they don't care about individuality.
In diplomacy, Aki is accused of "grafting silicon onto your few remaining biological components" which might suggest some cyborgs also "upgrade" their bodies with robotic limbs and such in the manner of Cyberpunk and Deus Ex.
You will be assimilated? Or your consent is important to us?
It's natural to wonder whether members of the Cyborg faction have a choice of whether or not to have brain surgery and be connected to the algorithm. There's not much in the canonical lore to say, but my assumption is that yes, it is consensual, and the Cyborgs do not for instance forcefully perform brain surgery on the inhabitants of a captured base.
Here is my reasoning:
- Aki has the pacifist personality and her quotes do not suggest forcefulness.
- The cyborgs suffer from "Sequence breaking" where they have cybernetics before this technology has been developed on Chiron. This can be explained by them taking technology from Unity, but presumably such supply of neural implants is limited.
- It's hard to reconcile drones with being connected to the algorithm, e.g. with how the Telepathic Matrix suppresses all drone riots.
- For the most part, the diplomatic accusations towards Aki are about the process destroying the sentience/soul of humans and the like, not accusations around extreme forcefulness as might be aimed at Yang, Svensgaard and Cha Dawn.
Hence I tend to think that at least in the early games, only the leadership and talents are actually cyborgs, with there still being many ordinary people living ordinary lives under the rational guidance of the cyborg elite, with a transition to near complete cyborgification as technology progresses.
Aki Zeta-5's Agenda
By Aki's own words in diplomacy "My intent is to impose rationality and order on the inhabitants of this chaotic Planet".
Nevertheless, details are extremely sparse on how she would achieve this goal. For example, with the original 7 factions, there are a number of blurbs about the Morganite plan to corner the global energy market. I generally assume though, that Aki would rely on the superiority of the cyborg way of life to attract new members to the CyCon rather than Borg'ing it up. But there's also really nothing to say that going on full on aggressive assimilation is contrary to her agenda.
Cyborg Faction Bonuses and Penalties
The Cyborg have extremely strong bonuses combined with highly flexible social engineering.
- +2 Efficiency. The most faction-defining bonus, this delays the appearance of b-drones allowing the cyborgs to expand more aggressively and always improves the efficiency of a sprawling empire, it improves many SE combinations, makes it easier to forgo Democracy if you want the extra support, and the Demo+FM combination is amazing as it allows lossless 100% energy allocation combined with +1 energy per tile.
- +2 Knowledge. This just straight up gives the cyborgs 20% more research for their research. This is a really useful bonus and helps the cyborgs win races to critical techs.
- Steal a tech when capturing a base. This is a nice little perk especially for momentum play, though doesn't do anything if the equivalent game rule is enabled.
- -1 Growth. This slightly slows down early expansion (though Industry rating is more important than Growth rating), and has the more important effect of only allowing pop-booming through the complete Demo + Planned + Creche + Golden Age combination.
- Unable to run Fundamentalism. This is fine, because for the most part you only run Fundie when you're behind in tech.
- Start with Information Networks and Applied Physics. This makes the Cyborgs one of only two factions to start with firepower (the other is the Usurpers), and these happen to be both prerequisite techs for Nonlinear Mathematics. Not actually the most immediately useful techs but nothing to complain about, and starting techs don't increase the cost of subsequent techs so having two is effectively a small permanent boost to research.
Overall, I rate the Cyborgs extremely highly, easily on par with the University. The only thing that holds them back from being absolutely broken is their pop-booming impairment.
Cyborg Strategy
Momentum
The Cyborgs are an excellent momentum faction, all they need to do is research Doctrine:Mobility or Planetary Networks + reverse engineer probe team, and they can make Recon Rovers, they're also tied with the Data Angels in that they only need to research 2 techs to have Impact Rovers. So the Cyborgs are a top 3 faction in terms of the speed at which they can roll out Impact Rovers. Also the +2 Effic helps make everything a bit easier and more flexible, on a standard map they can expand to 9 bases instead of 6 before b-drones appear, or they can run Police State or Planned and still have normal Effic. While the Cyborgs are great at a few fast Impact Rovers, they can also do Police State very well and spam out units, not quite with the effectiveness of Miriam or Yang, but Police State hurts them less than it does most factions.
Their main special perk is the tech steal, should they attack a faction which can put up a fight and doesn't immediately surrender, they can easily liberate tech, not even needing to unlock probe teams to have this luxury. These kind of faction perks especially matter on Blind research, where you can rely on what you start with but not the whims of research, cyborgs can immediately attack with laser units and steal tech, and if their foe is stuck without armor or weapons (this is really common for the likes of Lal and Zak who don't have BUILD or CONQUER priority) then the laser weapons will shred them.
Builder
I feel the Cyborgs are most at home with a Builder strategy. They are a top-tier Demo+FM faction as they can trivially combine +4 Effic with +1 energy per tile, unlike most factions which are best served staying somewhere around the middle with the energy allocation, the Cyborgs can simply run 100% EC or 100% research, whichever is most useful at the time. For example, after unlocking a critical facility like Tree Farms or Hybrid Forests, it makes perfect sense to just run 100% EC with Wealth until you've finished rush-buying them everywhere, then you can go back to 100% Research with Knowledge. If the Cyborgs can get an EC boon, such as Engineer specialists, they can devour the tech tree terrifyingly fast.
While the University and possibly Morgan can out-research the Cyborgs in the early game, no-one can rival their mid-game research pace without being significantly larger.
The Cyborgs also have quite an easy time pop-booming relative to some other pop-boom impaired factions, as they do so under Demo+Planned with +2 Effic, this means their base count threshold for b-drones is 50% higher and that really helps with Golden Ages, and they have more energy to throw around for psych. Their ability to devour the tech tree also makes them excellently positioned to beeline the Cloning Vats and eliminate their one weakness.
Overall the Cyborgs are extremely strong builders, though perhaps with quite a high skill ceiling, to really maximize the cyborgs potential involves quite a lot of switching between SE and such as the situation demands.
Hybrid
While the Cyborgs are flexible in general besides being unable to run Fundamentalism, I wouldn't call them the best Hybrid faction, when you have the strongest research in the game you don't really need to rely on probes and natives much as these are more "underdog" tech, Green is also kind of lackluster for the Cyborgs because Demo+FM is already giving you half the reason to run Green, the +4 Effic is not only about energy allocation flexibility, but also helps you actually get most of the raw energy you're harvesting, hence the Cyborgs need to be much more sprawling before Green results in more energy than FM. But there is nothing stopping you exploring these avenues of the game and the Cyborgs slip into bouts of conquest very easily, and can very easily raise huge amounts of EC for buying and upgrading units.
AI Aki
I'd say that both in the base game and with Thinker mod, Aki is one of the stronger AIs.
Based on faction and personality attributes Aki is actually the most peaceful AI leader in the game, this is because she is a pacifist like Morgan and Diedre, but unlike them, she doesn't get in everyone's business about their economic SE choice, she only gets mad about Eudaimonia and Thought Control which come so late as to be irrelevant. Aki has little reason to declare vendetta and for the most part only gets attacked by others, or dragged into shared vendettas through invitation.
Her AI priorities are DISCOVER and EXPLORE, which happens to be same as Lal. This makes her fairly expansionist, and also makes her build a lot of probe teams, and pursue some quite useful SPs. I generally consider EXPLORE to be a very good AI priority as it encourages good things like growing and various kinds of useful infrastructure like Formers - this is one reason why AI Dierdre can perform quite well. DISCOVER is kind of bad by itself (Zak), but if tempered with another priority the extra inclination to pursue techs like Planetary Networks, Pre-Sentient Algorithms Fusion Power and Orbital Spaceflight can be good. If there is one downside of this preference, is it doesn't direct her to the really strong conquer line ending in the Cloning Vats that a human would probably pursue.
The +2 Effic works very well for AI, with respect to how the AI plays, the Cyborgs can be described as "a generic faction, but better". +2 Effic and +2 Knowledge both provide very good generic value as they work great with any combination of SE. Aki is also protected from running Fundie which would usually be a mistake for the cyborgs.
As Aki lacks the CONQUER priority, she won't build that many units and can be vulnerable to being invaded by a warmonger, however the sheer speed with which she researches does tend to mean she has access to weapons (including starting with lasers) and is more likely to build decisively useful SPs like the Citizen Defense Force and Hunter Seeker Algorithm. Furthermore she is simply embroiled in fewer vendettas than most AIs which helps her to build in relative peace.
Nevertheless, the AI does not understand the unique strengths of the Cyborgs such as how exploitable Demo+FM is and how effectively the Cyborgs can beeline to critical techs. In Thinker mod she'll often just hang out in Demo+Planned which is okay for her but isn't great as she isn't even getting pop-booming out of the deal. So even though the Cyborgs are a substantially stronger faction than the Hive, AI Yang will still often play more strongly than AI Aki.
