The industrial revolution transformed the world entirely. Its most profound legacy, though, is not anything specific like electricity, motorized transport, or the computer, but the state of permanent technological revolution in which we now live, move, and have our being. There are some, it is true, like economist Robert Gordon, author of The Rise and Fall of American Growth, who argue that we should not expect future innovations to match what we have experienced in the past. But like the fabled salt machine at the bottom of sea, the tech industries continue to churn out innovations–smart phones, driverless cars, Wikipedia, delivery drones, solar panels, camera-based surgery–that quickly and significantly affect the lives and expectations of us all.
For more than two centuries, this ongoing technological revolution has consistently done two things.
- It has eliminated jobs by replacing humans with machines
- It has created new jobs
Agriculture offers a paradigmatic example of the first trend. In 1830, 83% of the workforce in the US was employed in agriculture. By 2014, the percentage working in agriculture, forestry, fishing, and hunting was down to 1.4%. Most of this reduction is due to the introduction of machines that in a few hours could plough, sow, gather, winnow, stack or store what used to take teams of workers days to accomplish.
From the start, the displacement of people by machines has caused problems. The original Luddites were English textile workers in the early nineteenth century who sought to protect their jobs by smashing the new weaving machines introduced by factory owners looking to save labour costs. Since then the same pattern of technology replacing or displacing workers has been repeated countless times. When the sort of work involved is boring, repetitive, and requires little skill or training, the loss is less likely to be lamented. But very often workers who identify with a specific trade, and pride themselves on skills acquired over many years, find themselves the victims of innovation. And this can happen very quickly.
