> So clearly you can have technological advances without any productivity growth.

A little perspective is required. From the 1860’s to the 1960’s we went from candles and horses to computers and the moon landing. In the past 50 years nothing comparable to electricity, automobiles, flight, space flight, antibiotics, refrigeration, computers, telephones, radio, nuclear power, etc. has been invented. We have only refined technology invented by our great grandparents. Our civilization is stagnant and incapable of producing the kind of people who can move us forward. And, when the population begins to decline, we’ll begin to regress. Our great grandchildren might only read about airplanes in books.
