Questionable ethics - Living Memory

[Infindox]

But they're the same thing; sentient synthetic life-forms. AI with self awareness, the ability to change and adapt, with desires and dreams, with emotions.

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.
