Why do you consider some changes to be useful and at the same time harmful?

Some changes can be considered useful because they drive progress, innovation, or improvements in quality of life, such as advancements in technology or social reforms. However, they can also be harmful if they lead to unintended consequences, such as job displacement, environmental degradation, or social inequality. The dual nature of change reflects the complexity of human systems, where benefits for some may come at a cost to others. Thus, evaluating change requires a nuanced understanding of its broader impacts.
