Naval drama in space with magical faster than causality travel.
AGI is the machine god mythos, or the insanity that sentient superiority results in an inevitable existential threat to humanity... because we are a monoculture on this planet after defeating all lesser contenders.
Going to space for stupid reasons like flag planting, or the failure to communicate how much resource wealth is really in space, even close by Earth with M-type asteroids.
I think AGI is very near and just a matter of mixing systems. An entire data center running a complex agent in a FORTH interpreter loop with a few guardrails is practically there if you have the resources and enough data.
