Increases in the efficiency of production, from Jethro Tull's 1701 seed drill to the robots coming in 2015, do not only create more things for less effort. They also free up the time that was once needed for labour. The greater use of robots will add a lot more time, much of it in the hands of skilled and educated displaced workers.

What will they do with this freedom? Most likely, some of them will find new jobs in industries which strive for efficiency. However, there should also be enough time to dedicate to activities economists typically disdain as inefficient but that people actually covet. Running fancy bakeries and providing more personal care fit in. So do travel, study, friendship, courtship, home baking and leisurely cake-eating. Think of it as the strudel benefit.

Ideally, governments and economists would be able to explain what is going on sufficiently well for people to relax about finding more things to manufacture with more efficiency.
