swayvil implies that our universe matches the kind depicted in Greg Egan's novel, Permutation City. In the second half of the book, the protagonists simulate a universe. That universe develops intelligent life that begin to threaten the simulation. So, the protagonists create an in universe representation of themselves - the 'invasion robot' that swayvil mentions - at the edge of the universe. So, by treating the NGC 7469 black hole's event horizon as equivalent to that 'edge of the universe' of the story, swayvil suggests that we have caught sight of ~god assembling a metatron from base components, on its way to convince us of its existence.
