That allowed them to track how breakthrough technologies impacted the exposure of workers in relevant occupations over time. Based on U.S. Census surveys from 1910 to 2010, the team found that an increase in technology exposure was linked to a decline in employment. These employees saw their wages slow down by more than twice as much as average workers in the same occupation with the same level of technology exposure. Even when their technology exposure did go up, their income didn't slow down as much as it did in other types of occupations. "Not all technology is bad for workers," Seegmiller says.
