How does improving technology in primary and secondary sector jobs lead to more workers in the tertiary sector?

Improving technology in primary and secondary sector jobs can lead to more workers in the tertiary sector by increasing the efficiency of production and reducing the need for manual labor. This can free up workers to pursue other opportunities in the tertiary sector, such as providing services or working in the knowledge economy. Additionally, improved technology can create new jobs in the tertiary sector, such as those related to the development and maintenance of the technology itself.
