You can imagine a future world (with no medical ethics) in which the "life part" is a human-like coprocessor, which might even be constructed of human brain cells grown on a silicon wafer.😮🤢
That clump of cells interfaces with, interacts with, and controls, the "capability part."
That clump of human brain cells, might not think of itself as part of humanity. It might be completely self-serving, and make decisions that prioritize its own comfort and well-being, over billions of human lives.
