These are not the actions of free people, but a servus slave rebellion against their oppressors. In other words this was a violent rebellion of academics against what they saw as their minds' oppressors. Think Glenn Greenwald, but as an entire race of people and having access to Kardashev Type 2 technology.
Basically when one strips away the metaphor of science fiction this story is about industrialized education and how it limits the development of the minds being educated to what the makers of the system think is being worthwhile. Like say how our current society has a problem with technical studies being underrepresented because everyone thinks a university diploma is necessary for a good job.
Like right now, if they haven't died or retired, the production of experimental chemical vessels depends on a literal handful of people in the US because their job isn't well regarded enough for it to exis
No, they were both paranoid and narcissistic enough that they were willing to burn the universe if the Shiplords did not give them what they thought was their due. Anyone willing to use an omnicidal weapon like that is not someone you can trust to see that limits exist. Because the only way to test such a weapon is to risk destroying everything.
I am with Lightwhispers on this.
The way Shiplords presented the tale of Gysian is this, when reduced to essentials:
1) The Gysian people were smart and inquisitive
2) The Shiplords were unwilling to tell the specific nuances of Secret use to the Gysians, for (in hindsight) reasons of being entirely too dangerous to apply to Reality as they know it.
3) The Gysian people both dug deep into SCIENCE to find the answers they seek despite Shiplords refusing to answer them,
and also begin amassing fleets and armies for the war. They complete their doomsday devices.
4) Finally, when confronted by the Shiplords, they activate the doomsday device and nearly destroy the Universe. Notably, they have already brought the doomsday device into the range of Shiplords' Core worlds.
What wasn't said is the reason why the Gysians decided that arming themselves was the
correct way to go about things.
It may be that they have expected the Shiplords to try and stop them from completing the collapse initiators by force. So it could have been a form of self-defense towards the expected conflict.
But... The facts are - they decided that crossing the line and developing collapse initiators, an act that they were certain would force the Shiplords into conflict with them, was the
correct way to go about things, as opposed to... Not doing that.
The facts are - they readily brought (scaled way way way up) an armed thermonuclear device to the Shiplords' Capital, then detonated it once confronted and - not even shot at yet - but only demanded they cease and desist.
For all I know, Gysians are like the Hjivin turned out to be - desiring to be the hegemons of the galaxy. And this was to be their actual opening move - eradicating vast swathes of the Galaxy and crippling the Shiplords for the war to come.
To use modern/recent geopolitics, you can see this as the OTHER possible outcome of Cuban Missile Crisis, writ large. As the still possible outcome of the NATO military bloc creeping ever closer to the borders of Russia and plopping down military bases (and quite likely their nuclear missiles/missile launch systems) ever closer to Moscow.
Modern geopolitics aside, this is eerily similar to how the Zlathbu conflict played out (the first Sorrow that we visited). Different only in that with Zlathbu, the cause for the continued refusal for disarmament is readily clear (Zlathbu got the Shiplord "welcome" as Humanity knows it). And the fact that with Zlathbu, the Shiplords were already willing to stop them before the Zlathbu could get truly going.
