Final answer:
New technologies can simplify and routinize some jobs, but they can also create jobs with greater variety and complexity.
Step-by-step explanation:
New technologies have the potential to simplify and routinize certain jobs, especially those that involve repetitive tasks. For example, tasks like bookkeeping, clerical work, and repetitive tasks on production assembly lines can be automated using computers. This helps in reducing costs and increasing efficiency. However, it is important to note that new technology can also lead to jobs with greater variety and complexity. For instance, the development of new software and systems create opportunities for employees to work on more creative and challenging tasks. Examples of such jobs include software development, data analysis, and cybersecurity. Ultimately, the impact of new technology on job roles depends on the industry and the specific tasks involved.
