Ray Kurzweil, an inventor and futurist, said to more than 3,000 attendees at the South by Southwest Interactive conference last week: "We are a human-machine civilization. Everybody has been enhanced with computer technology," noting how smartphones and other mobile devices and technologies have become a part of who we are. He added, "If we can convince people that computers have complexity of thought and nuance ... we'll come to accept them as human."
