What is a common effect of technological advancements on labor demand, particularly in terms of job displacement?

Technological advancements often change the way work is done, which can lead to job displacement. This means that some jobs may become less needed or even disappear because machines or software can do those tasks more efficiently. For example, when automated checkout machines were introduced in grocery stores, fewer cashiers were needed. While technology can create new jobs in different areas, it can also make it challenging for workers to find new positions if they lack the skills required for these new roles. Overall, while technology can improve productivity, it can also lead to uncertainty and change in the job market.
