A "black mirror" typically refers to a reflective surface that appears dark when not in use, such as a smartphone or television screen. The term gained popularity through the Black Mirror television series, which explores the darker aspects of modern technology and its impact on society. In a broader context, black mirrors can symbolize the dual nature of technology, reflecting both its benefits and potential dangers. They serve as a reminder of how devices can connect us while also isolating us, prompting discussions about our relationship with digital media and social networks.
