In a recent podcast discussion, Lynn Wu, professor at The Wharton School and AIB Affiliated Faculty, points out that “contrary to the popular notion that robots will replace human labor, we find robot-adopting firms employed more people over time. Any displacement of labor came from firms that did not adopt robots. These non-adopting firms actually lost their competitiveness — and they had to lay off workers.” Details of Wu’s study, based on looking at the performance of firms that purchased AI and robots over a 20-year period in Canada, will be published in the INFORMS journal Management Science.
The most surprising revelation from the study, however, was that AI and robotics adoption resulted in a reduction in management and supervisory ranks. “This is a class of people we did not expect robots to have an effect,” Wu says. “Because managers, by definition, supervise other human beings, so we really cannot replace their functions until the singularity occurs with artificial general intelligence.”
The decline in managers’ opportunities in the AI/robotics enterprise is the result of vast efficiencies introduced to processes that once required a cadre of managers to oversee. “There is less need for managers to supervise, ensuring that workers show up on time, inspect their work, etc.,” says Wu. “Robots can record precisely the work they have done, so there’s no agency costs, no fudging of the numbers.”
Another surprise is the fact that AI and robots boost employment with both low-skilled and high-skilled jobs. Rather, it is “middle-skilled” jobs that are threatened, Wu found. “Robots cannot directly substitute low-skilled workers such as pickers and packers,” she says. “A manager can potentially supervise many of these workers at a time.” For high-skilled workers, “the effect is a little bit less certain,” she continues. “They can manage themselves; these high-skilled workers know how to do their jobs better than their managers.” Read more via Forbes
