In 1980 you'd say that in 20 years the average office worker would be performing calculations on thousands of rows of data, generating charts, typesetting documents, creating full color presentations, doing business with clients in multiple continents and they'd wonder how people would cope with the increase in cognition required to do all that. But it's just button-pressing for most people.
In 2016 they'll say "we have a database with 4 billion data points and we need to infer customer behavior patterns from it". You'll say "Sure.", sit at a desk, click "Segment", click "Demographic: 18-21", click "Intersect", click "Products", click "Make Recommendations", click "Apply" and a discount coupon for "Justin Beiber's Comeback Tour" will be beamed directly into the eye sockets of anyone who bought canned salmon last fall.
I don't see a society where 80% programs, I see a society where 10% builds things for the other 90% and a huge part of the middle class will be automated out of existence. This, to me, is the big issue that will shape this generation and the next.
