Automation/ML Engineers work impact on other teams

I work for a tech start-up. We have teams whose work is composed of administrative, labor-intensive, manual work. Our engineering team is working on ML and automation models to alleviate the need for humans to do this work. Some of the engineers are anxious that the work they are doing will eliminate the need for their co-workers jobs on the other teams. Have any of you felt this way in your jobs, i.e. that your work might mean fewer employees are needed and you are torn/anxious about that? If yes, what has helped you work through this?
