A concept from Vernor Vinge's SF masterpiece series ''Across Realtime''

Human Technology evolves to the point where humans cease to exist in any form recognisably human.

(Less sanguinely) Vinge claims that: "Within thirty years, we will have the technological means to create superhuman intelligence. Shortly thereafter, the human era will be ended."
