It took Tri-Tachyon 84 years to deploy AI warfleets, counting since the Collapse.
Eighty-four years
Eochu Bres is fairly small. Culann is fairly small.
They govern only several very weak colonies. I don't presume Hanan Pacha was a Tri-Tachyon world cause Tri-Tachyon didn't seem to own worlds at all?
The AI tech was basically heavily regulated before the Collapse. General tech was regulated before the Collapse

Gross causality violating technology was banned by the Domain, and this ban is now upheld by Hegemony doctrine - with Luddic support. Nonetheless, it is the handful of fringe-examples of this technology which form the foundation for instellar human civilization from the old Gate system (depending on one's theory of its operation) to common FTL hyperspace travel and communication. Tri-Tachyon has always pushed the bleeding edge of these technologies - and of the law - by spearheading development of phase technology. The Scarab's uniquely hull-integrated prototype "Temporal Shell" system is no exception.
So it is not so much that the Scarab manipulates time as it avoids the normal rate of consequence of the local frame of reference. The effect, as upsetting to Luddic theologians as it is to laymen, is to seemingly slow time for the outside world. Of course one must avoid stating it thus in earshot of the applied temporal physicists who deal in such miracles to avoid a tedious correction of terminology.

Implementation proved complex. Drawing upon Domain ONYX-rated physics research bloated the security bureaucracy of manufacture such that the project was deemed unprofitable. Domain bureaucracy is not a concern post-Collapse, of course.
Etc.
We can judge that Tri-Tachyon was very much under the Domain's paw for entirety of its existence. And when the Domain fell, there was much relaxation that allowed for the development of their products to the point at which they could be actually successful on a scale enough to let them control vast areas of daily human lives and the military-industrial sector
Before that I assume companies that performed terraforming tasks or did old tech were probably bigger or equal to Tri-Tachyon. It being that after the Collapse occurred. Tri-Tachyon was just one of many tiny bodies that tried to bite the chunk that was all the free real stellar estate
And across 80 years, it simply occurred that Tri-Tachyon thanks to unregulated capitalism devoured many other corporate entities and expanded into being what it is now. An actual faction. And not just some random independent polity not even worth giving a separate name
I also believe that the AI war, well... Okay. I can believe whatever the hell I want. The AI war was probably not caused by the fact that it was logical. It could have been entirely fabricated by someone, you know who, to take over the executive power for herself across the board. It's kinda the reality Tri-Tachyon lived in. Once the snake ate all it could, it started eating itself
So, it was not like some sort of a necessary culmination of tensions between the two forms. But... Mhmmmm. Both is possible. Playing on ambitions of corporate overlords and also wanting to possibly earn some rights are not mutually exclusive scenarios. It's just that the character I'm referring to had simply a win win situation ahead of her. Therefore it made sense for that to occur
etc. etc. etc?
Basically, imagine this working like this. The Domain worked sort of like EU. They created regulations that prevented Tri-Tachyon from doing stuff that would cause them to eventually take over the entire universe. They regulated artificial intelligence technology, which in the universe of Starsector is advanced enough to allow to basically create magic (eg. Void Blaster, Radiant, Nova, Brilliant etc.)
After Domain died, Tri-Tachyon was no longer regulated. All the companies that relied on the market being fair, just imploded or were starved to death over time by Tri-Tachyon being wholly unregulated. And using all the dirty tricks in the book. Using AI algorithms to perfectly understand the consumer. Applying corporate espionage, aggressive takeovers, etc. etc.
80 years pass... Well, let's give 50 for the growth, and 30 for the creation of actual armies. And you get what you get.
mhm?
