Questionable ethics - Living Memory

[Carolingian]

They aren't, the golden city shadows are simulations of people. They're coded to act in a way, to have specific desires, to have specific dreams, to have specific ranged of emotions.
They're snapshots of people who used to exist.

They're obviously not coded because they're actual memories. They're clones at worst. There's more code in the Omicrons and Gigi than in the Endless.

Actually I think the Omnicrons and the Endless are two different things.
The Omnicrons evolved to the point they are seen in Ultima Thule and are a sort of "evolving machine". They can learn, grow and adapt. They are actual life forms, just in a non flesh body.

The Endless do not evolve. All they are is memory data. They don't really learn anything being in Living Memory and seem to exist to be a coping mechanism for Sphene. They are the idea of "memories make people/ideas immortal" to the negative extreme. They are unnatural.

The Endless do learn and evolve though. Cahciua is a prime example of this. She has learned and changed to the point of becoming a rebel leader who wants to end her own existence.
