Technology has caused the decline of our "social capital" (Sachs, 442). Instead of uniting as a people to make a difference, we are doing so by acquiring the most views or likes. Martin Luther King once said, “If you want to change the world, pick up your pen and write.” Technology has led us to develop an addiction to our devices, to the point where we have lost our sense of ourselves. Over time the best way to express yourself was face to face or through letters, now it's simply through a message or a tweet. Technology among adolescents can also “impair their cognitive abilities” (Sachs, 442). Excessive use of technology can cause the way we think and function to be altered.
