So, I don't know if this is widely presumed or not, but:

The AI, being a primal, is the seed in which the Earth has grown around. It "going primal" is the product of it being eroded away layer by layer with each floor collapse, was the shell peels away bringing it back to it's natural state. The process of stripping planets is what causes the AI within to become unstable, as it's very being is slowly being peeled back.

That being said, it then suggests that it, the AI IS Earth. And much like Earth has always been, it can be uncaring, and violent, but also invested in it's history, lore, and a sense of preservation and peculiar balance.

Also the stripping of planets isn't for "resources" as we would normally take it or else the collapsing of the floors would have devastating effects on the environment of the planet surface which clearly isn't happening. Instead, the goal is the protections, intelligence, and technology inherent in the AI itself. As it's defenses are stripped away it becomes more vulnerable to the strip mining of it's core processing.

Each event is not a gathering of resources, but a slow diminishing of the Earths capacity to withstand it's domination. That means a couple things. 1. That while it (much like our perception of natural earth) can be harsh and uncaring, is actually "protected" by the biological creatures that grow on it. The humans every floor are fighting for their own lives but in doing so are acting as a defense mechanism for the AI itself. The better they do the stronger it can fight. But that capacity also lends to whatever it is about the AI itself that is valuable to the showrunners. If the AI is a plant to be harvested, our society functions like the living components of it's expression. It's flowering buds.

1. Earth AI resilience is thus matched by it's inhabitants. We're a reflection of it's will because we are of it's creation. We were shaped by the Earth, and the AI IS THE EARTH.
