The employment landscape is constantly shifting. While agricultural jobs played a big role in the 19th century, a large portion of jobs today are in administration, sales, or transportation, and this is changing rapidly. As the composition of employment shifts, it eliminates some jobs and creates others. Structural changes in the economy will cause some jobs to decline quite quickly. In all cases, automation is likely the biggest culprit. For example, software that automatically converts audio to text will reduce the need for typists.
