These various upgrades have become available in a series of gradual, incremental steps over preceding decades, such that today, they are pretty much taken for granted.

Were a fully upgraded person of the 2080s to travel back in time a century and be integrated into the population, they would be superior in almost every way imaginable. They could run faster and for longer distances than the greatest athletes of the time; they could survive multiple gunshot wounds; they could cope with some of the most hostile environments on Earth without too much trouble. Intellectually, they would be considered geniuses – thanks to various devices merged directly with their brain.
