Abstract
We lay out the first general model of the interplay between intercellular competition, aging, and cancer. Our model shows that aging is a fundamental feature of multicellular life. Current understanding of the evolution of aging holds that aging is due to the weakness of selection to remove alleles that increase mortality only late in life. Our model, while fully compatible with current theory, makes a stronger statement: Multicellular organisms would age even if selection were perfect. These results inform how we think about the evolution of aging and the role of intercellular competition in senescence and cancer.

Note I came across it via this link which is not really saying what they model: https://science.slashdot.org/story/17/11/01/2324217/scientists-have-mathematical-proof-that-its-impossible-to-stop-aging
Thanks. At some point I'll have to dig into this and see if the same math would apply to AI/robots or not. It might have implications into whether to try for singletons or not.
