The discovery in 2290 of RapidGrow(tm) completed the last piece in the puzzle of immortality. RapidGrow(tm) used Nanites to speed cellular growth and to shape the human cortex. Through the process, a single cell was cloned then placed in a special Nanoassembly bay, modified to serve as an artificial womb. Over a two week period, the cell grew from embryo, to child, to mature adult. At the same time, the cerebral cortex was imprinted with the personality of a full grown human. Immortality was at hand.
