A citação canônica a que você está se referindo é:
Soldiers shouted, and the Cultists made warding signs, screaming to vanquish the unexpected demon. The liquid-silver flowmetal spire twisted and reshaped, billowing out at the end like an inverted umbrella, a parabolic dish of some sort.
A transmitter!
With a groan like a dying sea beast, the Central Spire convulsed and then vomited a flash of light, shooting a signal upward through the atmosphere like a scream out into space, where it would dissipate across the parsecs. Then the Central Spire collapsed, lost its integrity, and splattered into puddles across the broad, rubble-strewn plaza.
Um capítulo anterior deixa claro que Omnius pretende transmitir uma cópia de si mesmo para o céu na esperança de que uma futura civilização baixe (acidentalmente ou deliberadamente) uma cópia dele em uma forma capaz de desdobrar sua inteligência, iniciando assim a guerra de máquinas novamente.
Corrin was about to fall, because of them.
Before the two faulty copies struck him down, Omnius Prime had developed a perfectly acceptable means of escape, a way to allow the core copy of his evermind to survive. He had the ability to code all the information that comprised his entity into a giant datapacket. As a mere signal, not a gelcircuitry construction, it would be able to pass through the scrambler net. “Omnius” would drift across the galaxy until he found some receiver, anything that could download him. Anything he could inhabit.
Embora não seja explicitamente declarado, uma maneira de evitar que isso ocorra seria impedir que futuras colônias humanas possuam computadores poderosos o suficiente para que isso seja uma ameaça (cutucada, cutucada, piscada, wink )
Para registro, essa estratégia é bem-sucedida (aviso: spoilers)
