We could engineer cells to continuously report their status, perhaps by releasing vesicles into the bloodstream as real-time readouts of their functional state. Cells might incorporate built-in mechanisms to readily repair themselves or safely self-destruct if they become dysfunctional. Additionally, modular genomic “landing pads” could serve as predictable insertion points for new synthetic functions as they emerge. Together, these innovations would propel replacement beyond merely preserving health,
