Recently a new study was released by James Bessen, a professor at Boston University's Law School, that examined the impact of technology on employment levels. This study specifically looked at 317 various occupations between 1980 and 2013. The study found that industries that employed automation through technology actually saw an increase in the number of jobs that were created. For example, Bessen noted that automated teller machines were implemented by banks in the 1990s, yet the number of bank tellers has actually increase by 2% each year.
