[I Have No Mouth And I Must Scream] How Was AM Keeping Them Alive?

Title. Ted describes the humans as immortal, but it’s not exactly explained how they come back to life. 

Is he reconstructing their bodies? If so, *how*? I’m confused. 

Also did AM create an actual bird or was it the hurricane as the bird? Or was the bird like wires? I’m confused.

I assumed AM has something on the level of nanotechnology, something that can take a living body and repair it, alter it, and just generally do what it wants with. So, as they would age, those nanobots are just zooming around, repairing synaptic failures, shutting down biological changes that would allow aging, forcing the body to digest itself to stave off starvation, etc. 

I assumed the bird was something made up to look like a bird, mechanical or bio mechanical, intended to play with mammalian instincts left over from times when a sharp cry from above and the strobing light of beating wings meant death. He tells them to hunt it for food, then gives them piddling toy weapons, so he clearly doesn’t intend for them to actually eat it.

Not that our narrator is of the reliable sort… He does run in fear of things others can’t see, and they laugh at him for it, so the bird could look entirely different to the rest of the group.
