The idiom “a double-edged sword” aptly describes its impact, as it brings both positive and negative consequences. [I] While social media platforms enable people to connect across the globe and share ideas instantly, they also contribute to issues such as misinformation and reduced face-to-face interactions. [II]

One of the most significant benefits of social media is its ability to foster community and activism.
