Yes and no. The rapid pace of technology and globalization does cause some jobs to go away. Some fields, like manufacturing, use robotics and other automation to increase productivity, allowing companies to produce more with fewer workers. However, they still need human workers to operate and maintain the equipment, and many of these jobs are still in high demand—even if there are fewer of them.
Many skilled trades are less likely to go away. For example, electricians are needed almost everywhere, so these jobs are more resistant to automation or outsourcing.
Keep in mind that white-collar jobs can disappear too. Don’t let it discourage you from taking a blue-collar career path.
