How would you explain the disconnect between the advances in technology described in the news clip and the pace of real GDP growth?

In Silicon Valley at Alphabet’s X labs, people are working on transformative technologies that include driverless cars, high-altitude balloons that deliver the Internet to remote regions of the world, self-navigating drones, and flying wind turbines tethered to a ground station. But despite today’s advances in technology, our economic growth rate has slowed.
