“Why are there still so many jobs?,” asked MIT economist David Autor in a 2015 article on the history of workplace automation. Given that technologies have been automating human work for the past couple of centuries,“should we not be somewhat surprised that technological change hasn’t already wiped out employment for the vast majority of workers?”
As Autor explained in the article, the answer is based on an economic reality that’s frequently overlooked. “Automation does indeed substitute for labor - as it is typically intended to do. However, automation also complements labor, raises output in ways that lead to higher demand for labor, and interacts with adjustments in labor supply. … journalists and even expert commentators tend to overstate the extent of machine substitution for human labor and ignore the strong complementarities between automation and labor that increase productivity, raise earnings, and augment demand for labor.”
Professor Autor was co-chair of MIT’s Work of the Future Task Force, which was launched in the spring of 2018 to better understand the impact AI and automation on jobs. The Task Force released an interim report in September of 2019. Its overriding conclusion was that the likelihood that AI and automation would wipe out major workforce sectors in the near future was exaggerated.
However, it raised important reasons for concern, especially the rising polarization of employment and wage distribution over the past few decades, which has disproportionately benefited high-skilled professionals while reducing opportunities for mid- and low-skilled workers. The report emphasized that “at a time of historic income inequality, a critical challenge is not necessarily a lack of jobs, but the low quality of many jobs and the resulting lack of viable careers for many people, particularly workers without college degrees.”
The Covid-19 pandemic came a few months later, pretty much turning our world upside down.
