Passive income: NO

User Interface Testing is generally not a passive income stream. It requires active involvement in testing, reporting, and iterating on feedback. While automation tools can streamline some processes, they don't eliminate the need for human oversight and interaction. Most people in this field earn actively rather than passively, as the work is project-based and requires ongoing engagement. Only a few outliers, who might develop a highly successful testing tool or platform, could potentially earn passively. Myths include the belief that automation can fully replace human testers, which is misleading as human insight is crucial. Realistically, this becomes passive for those who create scalable testing solutions or platforms, but not for individual testers.
