An econtalk podcast, of course. At one point, Harford says,

one thing I learned is not to undervalue innovations that are important simply because they have become very, very cheap, so they’ve become ubiquitous. The other thing I learned was not to forget the way that inventions reshape organizations, reshape the way we live, reshape societies. Often in order to use an invention, take advantage of an invention, you need an awful lot of adjustment. The classic example, which will be well known, I think, to some EconTalk listeners, is Paul David’s essay on “The Dynamo of the Computer”, reflecting on how long it took electric motors to be adopted in manufacturing in the late 19th-early 20th century, because people had to completely readjust, reconfigure the factories, retrain the workers. I mean, just everything had to change in order to take advantage of this new technology. And initially when it was used, they tried to direct replacement to the steam engine–just rip out a big steam engine, replace it with a big electric motor, and that should be fine. And of course that doesn’t realize the gains. Because to really take advantage of these technology, we often have to change, and adjust the way we do things–the way we work, the way we live. Otherwise we don’t enjoy the benefits. And sometimes those changes can be–well, they are very hard to predict, but they are occasionally quite hard, quite wrenching.
