What does 'technical unemployment' refer to in the context of job changes?

The term 'technical unemployment' specifically refers to job loss or displacement that occurs when positions become automated or when technological advancements render certain skills obsolete. In this context, as machines and technology take over tasks that were once performed by humans, jobs may require less skill or become non-existent for certain workers, leading to unemployment in those sectors.

Automation often means that the tasks associated with particular jobs no longer need to be carried out by humans, which can lead to significant changes in the labor market and a shift in the types of skills that are needed. Workers may find themselves unable to secure employment because they lack the skills required for new job opportunities that are not affected by automation.

The other options do not accurately reflect the concept of technical unemployment. For example, jobs becoming more prestigious or the availability of jobs increasing do not necessarily link to the displacement caused by technological advancements. Similarly, higher demand for skilled workers pertains to a different phenomenon, focusing on the skills rather than the displacement caused by technology.
